  • 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.

  • Like STM32H7, now STM32F4/F7 clock drivers are binded by
    MFD stm32_rcc driver.
    This also allows to add reset support to STM32F4/F7 SoCs family.
    As Reset driver is not part of SPL supported drivers, don't bind it
    in case of SPL to avoid that stm32_rcc_bind() returns an error.
