Francois Ramu 29b0cd4278 drivers: clock_control: stm32h5 driver input vco range
Set the correct VCO input range for the PLL frequency
with each bit PLL1RGE of the PLL1CFGR register
This get_vco_input_range is similar to the stm32h7 one.

Kacper Dalach 305423ccb8 drivers: clock_control: stm32h5: Add MCO configuration
STM32H5 series lacked support for MCO configuration.
Added SOC_SERIES_STM32H5X to approperiate kconfig MCO source
configurations. Added new MCO sources from H5 series and
updated the clock_stm32_ll_h5.c with MCO configuration.

Kacper Dalach f9773859c4 drivers: clock_control: stm32h5: boot_clock_assert_fix
When the image is chain-loaded, clocks may already by initialized.
The driver was lacking support for already configured HSE and
PLL sources. When CONFIG_ASSERT=y get_startup_frequency was
failing since it did not recognize these sources.

It's the same issue that was addressed in #58109 for stm32u5.

Francois Ramu e802779d86 drivers: clock control: stm32h5 set the clock freq for voltage scaling
According to the stm32h5x product specifications, the values of the
voltage ragulator depends on the system clock as follows:
• VOS0 (Vcore = 1.35V) with CPU and peripherals running at up to 250 MHz
• VOS1 (Vcore = 1.2V) with CPU and peripherals running at up to 200 MHz
• VOS2 (Vcore = 1.1V) with CPU and peripherals running at up to 150 MHz
• VOS3 (Vcore = 1.0V) with CPU and peripherals running at up to 100 MHz

Benjamin Bigler 1889af9d9c drivers: clock_control: stm32: Fix switching to HSI
If clock frequency was already high and a ahb prescaler greater than 1
was used frequency could temporary become higher than allowed.

Wojciech Slenska 7271c3926f drivers: clock_control: stm32h5: Set HSI divider
By default HSIDIV is set to 0x01, so default frequency is 32 MHz.
This register should be always set based on dts value.

Francois Ramu 4a6a703f0f drivers: clock control for the new stm32h5 serie
Add the driver for the clock control of the new stm32h5.
See the corresponding Ref Man to get the clock scheme :
HSI, CSI, HSI48, HSE, LSE, and 2 or 3 PLLs
