4e97e25723 clk: clk_stm32fx: add clock configuration for mmc usage
MMC block needs 48Mhz source clock, for that we choose
to select the SAI PLL.
Update also stm32_clock_get_rate() to retrieve the MMC
clock source needed in MMC driver.

STM32F4 uses a different RCC variant than STM32F7. For STM32F4
sdmmc clocks bit are located into dckcfgr register whereas there
are located into dckcfgr2 registers on STM32F7.
In both registers, bits CK48MSEL and SDMMC1SEL are located at
the same position.

23a0641685 dm: reset: add stm32 reset driver
This driver is adapted from linux drivers/reset/reset-stm32.c
It's compatible with STM32 F4/F7/H7 SoCs.

This driver doesn't implement .of_match as it's binded
by MFD RCC driver.

To add support for each SoC family, a SoC's specific
include/dt-binfings/mfd/stm32xx-rcc.h file must be added.

This patch only includes stm32h7-rcc.h dedicated for STM32H7 SoCs.
Other SoCs support will be added in the future.
