Without this, setting a value of 0 leaves the bits unchanged rather than

The STM32H730 series has a variant built with SMPS. It uses
`stm32h730xxq.h` header file instead of `stm32h730xx.h`, which has the
SMPS macro defined.
This commit adds the `SOC_STM32H730XXQ` configuration option to allow
the build system include the proper header file. With this change,
boards can enable `CONFIG_POWER_SUPPLY_DIRECT_SMPS` to set up the power
supply for the CPU.

For the stm32 devices that have a HSI48 clock,
the driver enables it, like any other fixed clock,
if needed and supported by the serie.
For stm32L0, SYSCFG VREFINT is also required.

STM32h7 pllout frequency calculation overflows. In the
worst case pllsrc_freq can be 50Mhz and plln_mul 512 which will cause
an overflow of the intermediate result which leads to wrong frequency
returned. As no intermediate result can be bigger than 960MHz only the
order of operations is changed.

STM32H7 series offer alias addresses to access some registers that could
be accessed by the M4 core on dual core variants.
For instance RCC_AHB3ENR could be accessed at following offsets:
- 0x0D4: Accessible from both cores
- 0x134: Accessible from C1 (M7) core
- 0x194: Accessible from C2 (M4) core (if any)
For most single core H7 variants, the two first addresses were accessible,
but for some others (stm32h7ax/stm32h7bx), only the 'C1 accessible'
was available.
This fact used to be hidden by the use of LL API to access these registers,
providing the required abstraction (an mainly using the first alias
when possible to simplify implementation).

Fixes#40730.
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.
