562af8f65e global: move the soc component out of the common list
This MR removes the common dependency from every IDF components to the SOC component.

Currently, in the ``idf_functions.cmake`` script, we include the header path of SOC component by default for all components.
But for better code organization (or maybe also benifits to the compiling speed), we may remove the dependency to SOC components for most components except the driver and kernel related components.

In CMAKE, we have two kinds of header visibilities (set by include path visibility):

(Assume component A --(depends on)--> B, B is the current component)

1. public (``COMPONENT_ADD_INCLUDEDIRS``): means this path is visible to other depending components (A) (visible to A and B)
2. private (``COMPONENT_PRIV_INCLUDEDIRS``): means this path is only visible to source files inside the component (visible to B only)

and we have two kinds of depending ways:

(Assume component A --(depends on)--> B --(depends on)--> C, B is the current component)

1. public (```COMPONENT_REQUIRES```): means B can access to public include path of C. All other components rely on you (A) will also be available for the public headers. (visible to A, B)
2. private (``COMPONENT_PRIV_REQUIRES``): means B can access to public include path of C, but don't propagate this relation to other components (A). (visible to B)

1. remove the common requirement in ``idf_functions.cmake``, this makes the SOC components invisible to all other components by default.
2. if a component (for example, DRIVER) really needs the dependency to SOC, add a private dependency to SOC for it.
3. some other components that don't really depends on the SOC may still meet some errors saying "can't find header soc/...", this is because it's depended component (DRIVER) incorrectly include the header of SOC in its public headers. Moving all this kind of #include into source files, or private headers
4. Fix the include requirements for some file which miss sufficient #include directives. (Previously they include some headers by the long long long header include link)

This is a breaking change. Previous code may depends on the long include chain.
You may need to include the following headers for some files after this commit:

- soc/soc.h
- soc/soc_memory_layout.h
- driver/gpio.h
- esp_sleep.h

The major broken include chain includes:

1. esp_system.h no longer includes esp_sleep.h. The latter includes driver/gpio.h and driver/touch_pad.h.
2. ets_sys.h no longer includes soc/soc.h
3. freertos/portmacro.h no longer includes soc/soc_memory_layout.h

some peripheral headers no longer includes their hw related headers, e.g. rom/gpio.h no longer includes soc/gpio_pins.h and soc/gpio_reg.h

508fb79a26 uart: fix uart_tx_wait_idle to wait for fifo empty
In some cases, when data was just written into UART FIFO, transmitter
state could be still zero while the FIFO did contain some data.
This resulted in uart_tx_wait_idle occasionally returning before all
the data was sent out.
Fix by checking both UART transmitter state and TX FIFO count.

Fixes a bug that if application uses RTC_NOINIT variables but doesn’t

6dae5b206f reset_reason: fix setting wake stub entry point to 0x80000000
esp_reset_reason_init would check for reset reason hint, and
unconditionally set RTC_RESET_CAUSE_REG (which is also
RTC_ENTRY_ADDR_REG) to hint value 0, i.e. 0x80000000. However the ROM
code treats this value as valid deep sleep wake stub entry point, and
tries to jump to it.

Clear RTC_RESET_CAUSE_REG only if it contained a valid reset reason
hint, and simply set the register value to 0 when doing so. Also add
a check to esp_get_deep_sleep_wake_stub function that deep sleep wake
stub entry address must be in IRAM.

10c2cddddf sleep: fix flushing UARTs when entering deep sleep
Since 94250e42a0, UART output is suspended when entering sleep mode
(deep or light sleep). This makes sense for light sleep, where sleep
normally takes small amount of time, and flushing the UART would add
a lot of latency. But this breaks existing behaviour for deep sleep,
where UART output was previously sent out before entering sleep mode.

4359d5985e sleep: make sure input enable is set for EXT0/EXT1 wakeup
Since commit 94250e4, EXT0 wakeup mechanism, when wakeup level was set
to 0, started waking up chip immediately after entering deep sleep.
This failure was triggered in that commit by a change of
RTC_CNTL_MIN_SLP_VAL (i.e. minimum time in sleep mode until wakeup
can happen) from 128 cycles to 2 cycles.

The reason for this behaviour is related to the way input enable (IE)
signal going into an RTC pad is obtained:

    PAD_IE = (SLP_SEL) ? SLP_IE & CHIP_SLEEP : IE,

where SLP_IE, SLP_SEL, and IE are bits of an RTC_IO register related
to the given pad. CHIP_SLEEP is the signal indicating that chip has
entered sleep mode.

The code in prepare_ext{0,1}_wakeup did not enable IE, but did enable
SLP_SEL and SLP_IE. This meant that until CHIP_SLEEP went high, PAD_IE
was 0, hence the input from the pad read 0 even if external signal
was 1. CHIP_SLEEP went high on the 2nd cycle of sleep. So when
RTC_CNTL_MIN_SLP_VAL was set to 2, the input signal from the pad was
latched as 0 at the moment when CHIP_SLEEP went high, causing EXT0
wakeup with level 0 to trigger.

This commit changes the way PAD_IE is enabled: SLP_SEL and SLP_IE are
no longer used, and IE is set to 1. If EXT0 wakeup is used, RTC_IO is
not powered down, so IE signal stays 1 both before CHIP_SLEEP goes
high and after. If EXT1 wakeup is used, RTC_IO may be powered down.
However prepare_ext1_wakeup enables Hold on the pad, locking states
of all the control signals, including IE.

8c307a5720 sleep: fix deadlock in esp_timer_impl_advance after light sleep
When light sleep is started, the other CPU gets halted using DPORT
stall mechanism. This can happen while it is inside an esp_timer
critical section, which may lead to a deadlock. This change adds
functions to take and release esp_timer lock before entering
DPORT critical section, preventing the deadlock.

Updated unit test to check this functionality for light sleep.
