The SDMMC1 peripheral is used for SD-cards (default on ST boards), or
eMMC cards. For the moment it uses the fixed clock ck_flexgen_51, until
clock driver is available.

Add the configuration node for SD-card support on STM32MP257F-EV1 board.
For the moment it uses a fixed regulator for vmmc, and vqmmc is skipped
until regulator driver is available.
