The STM32H7, STM32F7, STM32L4 and common STM32 SDIO/SDMMC drivers failed to program the WIDBUS bits when switching MMC/eMMC cards to 4-bit mode, and the MMC transfer clock presets were hardwired to 1-bit bus width. Add CLOCK_MMC_TRANSFER_4BIT to the common SDIO clock enum, add 4-bit MMC clock presets, and update stm32_widebus() to use modifyreg32/ sdmmc_modifyreg32 to set the host controller bus width.
