Current ESP32 clock system is mixed with RTC labeling/registers,
but it doesn't implement a real-time clock (RTC) driver.
To avoid confusion and allow adding a proper RTC driver later,
this commit renames the existing RTC interface to CLOCK and make
it as a subsystem without any peripheral attached to it.
This better reflects its actual purpose as a general clock controller.

Enables sleep mode (PM3) on RW61x. The driver
re-enables the wdt on wake-up based on the previous
configuration. Note that the wdt counter value always
resets to the max window value on wake-up

Add support for the STM32WB0 series to the existing STM32 driver for
Independent Watchdog peripheral.
NOTE: this commit only includes basic support for the watchdog.
STM32WB0 specificities such as the different possible clock sources, LSI
frequency measurement or window support are left for future implementation.

Reset the watchdog back to the initial state before enabling the
expiry interrupt. This prevents the watchdog expiring immediately if
there is a long gap between `wdt_install_timeout` and `wdt_setup`.

default watchdog initialization disable counting in EM1, EM2 and EM3
modes. If user use the WDT_OPT_PAUSE_IN_SLEEP flag via the watchdog api,
all 3 EM modes must take this flag into account to avoid wdt count
being frozen if we don't want to.

The correct procedure to reload the T0 timer is:
1. Load TWDT0 register with the new value or write 1 to RST bit in
T0CSR register to load the old value.
2. Wait until RST bit in T0CSR register becomes 1.
3. Wait until RST bit in T0CSR register becomes 0.
The current watchdog driver misses step 2.
Fix the issue in this commit.

In order to ensure that watchdog channels are freed in proper
driver state, synchronization in form of simple loop needs
to be added after stopping. In no irq variant, it is already done
on nrfx level. NRFY function can be replaced by NRFX one in
the future.

The STM32 IWDG is a single channel watchdog, and therefore should be

instead of overwriting previous values.
