fafaa58240 drivers: clock: stm32: support STM32_CLOCK_DIV()
Support specifying divided clock buses by introduction of
STM32_CLOCK_DIV(div) macro. This macro can be used in devicetree to define
clock source of peripherals.

HSE is selected in devicetree using:

   <&rcc STM32_SRC_HSE ...>;

HSE/2 can now be selected with:

   <&rcc (STM32_SRC_HSE | STM32_CLOCK_DIV(2)) ...>;

This allows to use clock_control_get_rate() API in peripherals in order to
get desired clock rate.

dc5527721a drivers: clock_control: remove '&' when assigning clock_control_xxx_init
Remove address-of operator ('&') when assigning `clock_control_xxx_init`
function pointer in `DEVICE_DT_INST_DEFINE` macro.

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

fb60aab245 drivers: migrate includes to <zephyr/...>
In order to bring consistency in-tree, migrate all drivers to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

ed9cb841c3 drivers: clock_control: Refactor drivers to use shared init priority
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.

The bit RCC_MC_APB3ENSETR_PMBCTRL and RCC_MC_AHB5ENSETR_AXIMC

Convert clock_control drivers from:

    DEVICE_AND_API_INIT -> DEVICE_DT_DEFINE

As part of this we also changed STM32_CLOCK_CONTROL_NAME to be based on
devicetree.

e18fcbba5a device: Const-ify all device driver instance pointers
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:

@r_const_dev_1
  disable optional_qualifier
@
@@
-struct device *
+const struct device *

@r_const_dev_2
 disable optional_qualifier
@

-struct device * const
+const struct device *

Fixes #27399

37c13eec7a drivers/clock_control: stm32: Factorize series specific code
RCC device could be common to various STM32 series.
Until now, PLL handling code was set in series specific files,
even if it was driving the same device than another series.
Minimize code duplication by factorizing code between series
when possible.
With this change, some series get additional features by getting
access to code developed for other series.

Additionally, while renaming the files, remove the non informative
'x' to minimize file name length
