cf87e114cb deep_sleep: on S2 disable the brown out detector before deep sleeping
On S2 the brown out detector would occasionally trigger erroneously during deep sleep.

Disable it before sleeping to circumvent this issue.

7c5afa262d deep sleep: Calculate RTC CRC immediately before deep sleep, without using RAM
Fix for issues where RTC FAST memory is updated as part of going into deep
sleep. Very high risk if heaps are in RTC memory - in particular task stacks
may be in RTC memory, but also other variables.

Also fixes potential concurrency problems as RTC FAST memory is not accessible
by CPU during the CRC calculation itself.

Method:
- Disable interrupts (currently for single core only, will need update for S3)
- Load all registers before calculating CRC or going to sleep

31cd3f1294 esp32s2: suspend UART output using XOFF before entering light sleep
Same logic as for the ESP32, except two changes:

* need to set UART_SW_FLOW_CON_EN bit for UART_FORCE_XOFF to take
  effect
* need to check if the peripheral is not clockgated and out of reset

91841a53ff WDT: Add LL and HAL for watchdog timers
This commit updates the watchdog timers (MWDT and RWDT)
in the following ways:

- Add seprate LL for MWDT and RWDT.
- Add a combined WDT HAL for all Watchdog Timers
- Update int_wdt.c and task_wdt.c to use WDT HAL
- Remove most dependencies on LL or direct register access
  in other components. They will now use the WDT HAL
- Update use of watchdogs (including RTC WDT) in bootloader and
  startup code to use the HAL layer.
