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.

3369f15fa3 soc/rtc: don't power down BIAS_I2C along with APLL if other PLL is used
If enable == false, and SOC_CLK_SEL == PLL, the code would would
erroneously set RTC_CNTL_BIAS_I2C_FORCE_PD. This change fixes the logic.

f22c681c1c soc/rtc: raise core voltage when 80MHz flash frequency is used
To achieve reliable operation with GD flash at 80MHz, need to raise
core voltage.
This causes the following current consumption increase:

At 80MHz: from 29mA to 33mA
At 160MHz: from 41mA to 47mA

Test conditions: 2 cores running code from IRAM, remaining peripherals
clock gated.

eb5752c635 esp_restart: fix possible race while stalling other CPU, enable WDT early
Previously esp_restart would stall the other CPU before enabling RTC_WDT.
If the other CPU was executing an s32c1i instruction, the lock signal
from CPU to the arbiter would still be held after CPU was stalled. If
the CPU running esp_restart would then try to access the same locked
memory pool, it would be stuck, because lock signal would never be
released.

With this change, esp_restart resets the other CPU before stalling it.
Ideally, we would want to reset the CPU and keep it in reset, but the
hardware doesn't have such feature for PRO_CPU (it is possible to hold
APP_CPU in reset using DPORT register). Given that ROM code will not use
s32c1i in the first few hundred cycles, doing reset and then stall seems
to be safe.

In addition to than, RTC_WDT initialization is moved to the beginning of
the function, to prevent possible lock-up if CPU stalling still has any
issue.

f11ad0c904 soc/rtc: fix spurious warnings about XTAL frequency on startup
1. Make sure that 8MD256 clock used to estimate XTAL frequency is enabled
   before trying to use rtc_clk_cal_ratio.
   This fixes "Bogus XTAL frequency: 0 MHz" warnings after software reset.

2. Don't call rtc_clk_xtal_freq_estimate if XTAL frequency is already
   known. This reduces startup time after deep sleep or software reset.

3. Compare known XTAL frequency and estimated one before printing a
   warning. This fixes "Possibly invalid CONFIG_ESP32_XTAL_FREQ setting
   (40MHz). Detected 40 MHz." warnings.

6d4ed4ff6c soc/rtc: wait for SLOW_CLK cycle when switching CPU clock
Previous implementation waited for 20us after setting
RTC_CNTL_SOC_CLK_SEL_XTL register, using ets_delay_us, assuming that
the CPU was running at XTAL frequency. In reality, clock switch happened
on the next RTC_SLOW_CLK cycle, and CPU could be running at the previous
frequency (for example, 240 MHz) until then.
ets_delay_us would wait for 20 us * 40 cycles per us = 800 CPU cycles
(assuming 40 MHz XTAL; even less with a 26 MHz XTAL).
But if CPU was running at 240 MHz, 800 cycles would pass in just 3.3us,
while SLOW_CLK cycle could happen as much as 1/150kHz = 6.7us after
RTC_CNTL_SOC_CLK_SEL_XTL was set. So the software would not actually wait
long enough for the clock switch to happen, and would disable the PLL
while CPU was still clocked from PLL, leading to a halt.

This implementation uses rtc_clk_wait_for_slow_cycle() function to wait
until the clock switch, removing the need to wait for a fixed number of
CPU cycles.

05a0fbd49b soc/rtc: add a function to wait for slow clock cycle
Some RTC features are synchronized to RTC_SLOW_CLK, so sometimes
software needs to wait for the next slow clock cycle.
This function implements waiting using Timer Group clock calibration
feature.

5a88f90a33 soc/rtc: warn if detected XTAL frequency does not match configured one
Since 9a8c0392, XTAL frequency is set to 40MHz by default, and users
of 26MHz boards need to select 26MHz manually. Most users are not aware
of this change, and existing getting started guides do not mention that
XTAL frequency needs to be set for some boards. So users are left with
garbage output from UART without any clue what to check.

This change adds a warning in case specific XTAL frequency was set, and
it does not match automatically detected one. This should help users
fix the issue.

    When CPU starts, if reset reason is CPU reset, disable those clocks

    useless clocks.
    These peripheral clocks must be enabled when the peripherals are
    initialized and disabled when they are deinitialized.
