extend deep sleep APIs
This adds the following APIs to enable various wakeup sources:
- esp_deep_sleep_enable_timer_wakeup
- esp_deep_sleep_enable_ulp_wakeup
- esp_deep_sleep_enable_ext0_wakeup
- esp_deep_sleep_enable_ext1_wakeup
And an API to start deep sleep:
- esp_deep_sleep_start
Add an API to control which peripherals are kept enabled in deep sleep mode:
- esp_err_t esp_deep_sleep_pd_config
Also rolled an update of rtc_io header comments into this MR, as I had to add `slpie`, `slpsel`, and `hold` fields into `rtc_gpio_desc_t` struct.
Deep sleep unit tests don’t do anything useful in CI context because we don’t have a way to check reset behavior (time till reset, reason for reset) in CI environment, yet. Also for external wakeup we would need to control some ESP32 pins from the test environment.
Currently there is one known issue:
- RTC Fast memory may be isolated from the bus after deep sleep reset. We work around this by setting FORCE_NONISO flag in RTC power control register. This is non-optimal and we will keep looking for the reason why isolation gets enabled.

deep sleep: set pin configuration right before entering deep sleep
This change allows setting pin configuration for EXT1 wakeup depending on the state of RTC_PERIPH power domain:
- if peripherals are enabled (due to another wakeup mode, or due to esp_deep_sleep_pd_config call), we can keep internal pullups/pulldowns enabled
- if peripherals are disabled, pullups and pulldowns need to be disabled as well
Also add comments about the purpose of registers being configured.

deep sleep: RTC fast memory may be disconnected after deep sleep wakeup
This adds a workaround for a bug that following deep sleep wakeup, ISO (bus isolation) signal may be set for RTC fast memory.
We set FORCE_NOISO bit in RTC_CNTL_PWC_REG until we find out what is causing ISO signal to be set.

When ESP32 wakes up from deep sleep, flash is accessed an approximately 900us after power on.

Merge branch 'bugfix/rom_int_functions' into 'master'
Fix broken WiFi due to intr allocation code.
TL;DR: The dynamic interrupt allocation code fixed something up to the point it broke. This code breaks off the broken code, fixing everything.
The dynamic allocated interrupt patch also fixed a bug in FreeRTOSs interrupt handling for two cores, which caused the two cores to (most of the time) have exactly the same interrupts enabled. This made WiFi fail: it would wait on a semaphore but never figure out the other core had set the semaphore, so it would keep waiting in the idle task for ever. This was caused by both the cross-core interrupt as well as the tick interrupt being disabled.
The culplrit for this appeared to be the WiFi driver, which enabled a FRC2 interrupt. The code enabling this, through a respectable amount of defines, called a rom function which called a HAL function... which was configured in such a way that it worked okay if both CPUs happened to have the same interrupts set, but broke as soon as that was not the case, possibly setting only the interrupt that was enabled and clearing all others.
The fix for this is to not use the ROM functions, but provide our own instead. Fortunately, this can be done without changes in the WiFi libs.
This MR also addresses a potentially dangerous ESP_LOG as well as some, according to the ISA document, needed rsyncs in the interrupt enable/disable code. It also marks int 9 and 10 as reserved, the WiFi code seems to use this.

Merge branch 'feature/select_default_uart' into 'master'
UART console selection
This change adds a set of menuconfig options to set custom UART#, baud rate, and pins, for console output.
Ref. TW8146
Also includes the following changes:
- `uart_tx_wait_idle`: fix issue with last character not transmitted. ROM function `uart_tx_wait_idle` may have a bug which causes the function to return before the final character is fully transmitted. This replaces `uart_tx_wait_idle` declaration with a static inline definition which fixes the issue. Also replaces the use of `uart_tx_flush` with `uart_tx_wait_idle` in `esp_restart`, to remove garbage in console output on restart.
- `rtc_printf` is temporary replaced with a no-op, pending a new release of librtc.a. Current release assumes that UART0 is used for output,
and switches UART0 baud rate while doing frequency changes and printing some log output. This doesn’t work if a different UART is used for output.
- disable boot watchdog only after starting the main task. Boot watchdogs were disabled very early in startup code. It was possible to introduce an infinite loop anywhere in the many functions called from startup code, and this would not be detected by interrupt watchdog and task watchdog. This change postpones disabling of boot watchdogs to the point when the scheduler is running. Also replaces register expressed using integer address with a name. This change is not directly related to the previous ones, but was found while debugging UART selection features.
