Confusion here is that original ROM has two functions:
* SPIReadModeCnfig() - sets mode, calls enable_qio_mode/disable_qio_mode
* SPIMasterReadModeCnfig() - As above, but doesn't set QIO mode in status register
However we never want to use the ROM method to set/clear QIO mode flag, as not all flash chips work this way. Instead we
do it in flash_qio_mode.c in bootloader.
So in both cases (ROM or "patched ROM") we now call SPIMasterReadModeCnfig(), which is now named
esp_rom_spiflash_config_readmode().
Fix uart tx function block issue
To enable tx empty interrupt each time the tx ringbuffer get filled, so that tx function will not block if tx data length is larger than tx ringbuffer size.

Enable checks for encrypted flash in OTA
Even if firmware is compiled without CONFIG_FLASH_ENCRYPTION_ENABLED.
Rationale: CONFIG_FLASH_ENCRYPTION_ENABLED controls whether boot loader generates keys for encryption or not, but flash encryption can be configured externally. With this change, it's possible to have boot loader not generate keys but still have encryption working.
Also fix use of it->part

Introduce soc component, add source of rtc_clk and rtc_pm libraries
This MR adds parts of the RTC library source code (initialization, clock selection functions, sleep functions). WiFi-related power management functions are kept inside the precompiled library. Most of RTC library APIs have been renamed.
Default CPU frequency option in Kconfig is set to 160MHz, pending qualification of 240MHz mode at high temperatures.
Register header files are moved into the new soc component, which will contain chip-specific header files and low-level non-RTOS-aware APIs (such as rtc_ APIs). Some of the files from ESP32 component were also moved: cpu_util.c, brownout.c, and the corresponding header files. Further refactoring of ESP32 component into more meaningful layers (chip-specific low level functions; chip-specific RTOS aware functions; framework-specific RTOS-related functions) will be done in future MRs.

Bugfix/flash busy check wait spi idle
This branch moves some ROM SPI flash driver to IDF to fix bug in Wait_SPI_Idle() function.
Also it applies code style rules of IDF to integrated ROM driver sources.

Even if firmware is compiled without CONFIG_FLASH_ENCRYPTION_ENABLED
Rayionale: CONFIG_FLASH_ENCRYPTION_ENABLED controls whether boot loader
generates keys for encryption or not, but flash encryption can be
configured externally. With this change, it's possible to have boot
loader not generate keys but still have encryption working.
Also fix use of it->part
1) fixed SPI_read_status: added check for flash busy flag in matrix mode
2) fixed SPI_page_program: enable write before writing data to SPI FIFO
3) SPI flash ROM funcs replacement is controlled via menuconfig option
CI: add reset between running each unit test cases
Unit test is designed to detect bug **within** each test case. Therefore we'll reset between each case to provide a clean context. We will later add stress cases to run unit test cases together to detect potential bugs.

esp32: initialize cross-core interrupt in single core mode
The software interrupt originally used as the cross-core interrupt is
now also used to yield from a FreeRTOS critical section; therefore it
must be initialized for single core mode as well.

fix warnings generated by ESP_ERROR_CHECK(variable) in release builds
This uses the same pattern as “assert” in release builds to silence the
warning. At the same time, we make sure that if a statement is wrapped
into ESP_ERROR_CHECK, it is executed in release build as well.

spi_flash: fix race condition in s_flash_op_complete access
Flash operation complete flag was cleared by the CPU initiating flash operation. If the other core was running an ISR, then IPC task could be late to enter the loop to check `s_flash_op_complete` by the time next flash operation started. This would cause a deadlock, as the IPC task would still be waiting for `s_flash_op_complete` to be set (which was already cleared by the next flash operation), while the flash operation task would be blocked waiting for IPC task to set `s_flash_op_can_start`.
If the flag is cleared on the CPU waiting on this flag, then the race condition can not happen.

Fix timing adjustment needed for higher speeds of SPI master bus.
Ref https://github.com/espressif/esp-idf/issues/363 . It was found out the master SPI driver didn't exactly calculate the delay compensation needed, breaking 20 and 26MHz full-duplex mode. This fixes these use cases. We also found out 40MHz full-duplex routed over the GPIO matrix does not work because of a hardware quirk; this MR adds a check/error for that case until we find a workaround.

If static tx buffer is selected, WiFi tx buffers are allocated when WiFi is initialized and released
when WiFi is de-initialized. If dynamic tx buffer is selected, WiFi tx buffer is allocated when tx
data is delivered from LWIP to WiFi and released when tx data is sent out by WiFi.
The size of each static tx buffers is fixed to about 1.6KB and the size of dynamic tx buffers is
depend on the length of the data delivered from LWIP.
If PSRAM is enabled, "STATIC" should be selected to guarantee enough WiFi tx buffers.
If PSRAM is disabled, "DYNAMIC" should be selected to improve the utilization of RAM.
Fix finding location of ISR stack space for CPU1
Up to now, the CPU1 interrupts erroneously used the area *after* the ISR stack region, leading to bugs in BT Classic. This fixes that.

SPI flash operations lock for shorter periods
Based on bug report here:
https://esp32.com/viewtopic.php?f=13&t=1489&p=6816#p6773
Long SPI flash erase (and possibly write/read) cycles block all tasks on both CPUs for an extended period, and can lead to WiFi dissassociation (and general priority inversion.)
This MR inserts preemption breaks into large operations (all erases, writes every 8KB, reads every 16KB).
Overhead of a single spi_flash_guart_start()/spi_flash_guard_end() cycle measured at approx 67us (assuming no preemption.)

Error handling in NVS initialization
Previously nvs_flash_init worked under an assumption that there should always be at least one free page available. This is true during normal operation, but in some cases (such as when changing application partition table from a non-OTA to an OTA one), NVS partition may get truncated, which will cause empty pages to be lost.
This MR adds error checks for this condition, and updates code which calls `nvs_flash_init` to check for the return code.
For most examples, a simple `ESP_ERROR_CHECK` is added around `nvs_flash_init`. For NVS examples and the OTA example, more robust error handling is added.
This change also removes nvs_flash_init calls from examples which don't use NVS.
