490bf29767 esp32s2: fix enabling 32k XTAL clock
On the ESP32S2, rtc_clk_cal(RTC_CAL_RTC_MUX) measures the frequency
of the 90kHz RTC clock regardless of the selected slow clock
frequency. Keep track which clock is selected and pass the argument
to rtc_clk_cal accordingly.

fix clock choices

update rtc 32k xtal code for s2

missed api in rtc.h

bootloader_clock: update for S2

74ac618287 soc/rtc: update frequency switching APIs to match the master branch
esp32s2 code was based in IDF v3.1, and used outdated APIs.

Closes IDF-670

ESP32-S2 only supports 40MHz XTAL and doesn't have XTAL autodetection.

fb72a6f629 bootloader: add definition of esp_clk_apb_freq
Commit 8cd04c80 has added a dependency of efuse component on
esp_clk_apb_freq, however there was no definition of this function in
the bootloader context.

Cleaned up header files from unnecessary headers (releated to soc/... headers).

178e5b25e6 bootloader: check previously used clock frequency at run time
In the situation when bootloader was compiled for 240MHz, and app was
compiled for 160MHz, and the chip is a revision 0 chip, the
bootloader will assume that the application has also been running at
240MHz. This will cause the chip to lock up later. Modify this to use
a run time check of DPORT_CPUPERIOD_SEL, which indicates which of the
PLL frequencies was used.

Closes https://github.com/espressif/esp-idf/issues/2731.

f7df532ec0 bugfix/rtc_clk_32k_bootstrap: Fix starting 32k RTC
1. External 32kHz crystal is started for too long or it may not start at all. It is often observed at the first start.
2. At the first start, it is possible that the crystal did not start. And the recorded period was recorded as 0. Which led to a division error by zero during the transition to the deep sleep mode (Maybe somewhere else).
3. Added a unit test to test a new method of oscillation an external crystal.
4. Added a new method of oscillating of an external crystal. The legs of the crystal are fed with a 32 kHz frequency.

The new method eliminates these errors.

Added unit test: `\esp-idf\components\soc\esp32\test\test_rtc_clk.c`: `make TEST_COMPONENTS=soc`
- 8 Test starting external RTC crystal. Will pass.

`Bootstrap cycles for external 32kHz crystal` - is specified in the file Kconfig by default 100.

QA tested a new method of oscillation the crystal on 25 boards. The supply of square waves on the crystal showed a 100% result in contrast to the previous method of launching the crystal. After the tests, the old method was deleted.

c69af42b96 esp32: Fix backwards compatibility for pre-v2.1 bootloaders
Older bootloaders don't set RTC_XTAL_FREQ_REG or call rtc_clk_init(),
app needs to pick this up.
