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.

7e2a3da643 esp32: Fix not the right time spent in a deep sleep
Before entering the deep sleep, the RTC and FRC counters are synchronized. Updating the boot_time.
Added a unit test for this case.
Fixed warnings for MULTIPLE_STAGES

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.

1e9bb5bb7c esp32: Deactivate wakeup trigger after first wakeup
The files updated according to code review discussions.
In the sleep_modes.c removed immidiate disable of ULP  mode and leave just trigger deactivation.
The esp_sleep.h is updated to have the same defines for source as esp_sleep_wakeup_cause_t.
Updated documentation in sleep_modes.rst file to include cross references.
Some minor changes in test_sleep.c unit test.

2d90da0817 esp32: Deactivate wakeup trigger after first wakeup
The timer wakeup function once activated cannot be disabled later using existing api. If user wants to use different wakeup sources after first sleep but it does not work. This change disables timer wakeup trigger in configuration that will be set into appropriate RTC registers in esp_light_sleep_start() function.

Added function esp_sleep_disable_wakeup_source() to deactivate wakeup trigger for selected source.
Updated documentation for this function in sleep_modes.rst file to pass make html.
Updated unit test to check this functionality for light sleep.
The test_sleep.c unit test is updated to add reliability for auto unit testing.
