Enable the RTC-domain and main digital regulators early in clock init,
then load and program the factory/runtime calibrated bias values for
high-power and low-power regulators into the PMU. This ensures the
correct voltage/current settings for stable, low-noise clock operation
in active, modem and sleep modes.

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.

Remove address-of operator ('&') when assigning `clock_control_xxx_init`

This change aims to maintain consistency among the drivers in
`drivers/clock_control`, ensuring that all function pointer assignments
follow the same pattern.

This WDT is responsible for monitoring the external

the hardware automatically switch to RTC_RC_SLOW

The RTC subsystem in espressif's SOCs, among other tasks
is responsible for clock selection for CPU and for low
power domain clocks such as RTC_SLOW and RTC_FAST.
This commit allows for proper clock source and rate
selection for CPU, using the espressif,riscv and
espressif,xtensa-lx6/7 bindings.
It also enables clock selection for RTC_FAST and RTC_SLOW,
that impacts some peripherals, such as rtc_timer.

Refactors all of the clock control drivers to use a shared driver class
initialization priority configuration,
CONFIG_CLOCK_CONTROL_INIT_PRIORITY, to allow configuring clock control
drivers separately from other devices. This is similar to other driver
classes like I2C and SPI.
Most drivers previously used CONFIG_KERNEL_INIT_PRIORITY_OBJECTS or
CONFIG_KERNEL_INIT_PRIORITY_DEVICE, therefore the default for this new
option is the lower of the two, which means earlier initialization.
The even lower defaults for STM32 and Arm Beetle are preserved by
SoC-family level overrides.
