This joins all clock control handling to same source
by using hal clock functions. It also brings ESP32C3
clock support.

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.

Disable RTC WDT enabled (by default) by 2nd stage bootloader in ESP-IDF.
This WDT timer ensures correct hand-over and startup sequence from
bootloader to application.
Enabling bootloader caused system clock initialization to fail
when clock rate is greater then 80MHz. This also fixes
esp32 clock source code.

Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.
A coccinelle rule is used for this:

- Support PLL for Higher Frequencies 80,160,240 MHz
- Support XTAL Frequencies 26MHz, 40MHz
- Clock Driver can't be disabled, because all of the other drivers
will depend on it to get their operating Frequency based on chosen
clock source (XTAL/PLL).
- Add needed references to BBPLL i2c bus ROM functions.
- Add `rtc` node to Device Tree.
- Since All Peripherals Frequency is depending on CPU_CLK Source,
`clock-source` property added to CPU node
