stm32mp1: board: add support of CONFIG_ENV_IS_IN_MMC

Browse Source 
Add support of CONFIG_ENV_IS_IN_MMC in env_get_location, used for
all mmc device (SD card and eMMC).
The 2 configs CONFIG_ENV_IS_IN_MMC and CONFIG_ENV_IS_IN_EXT4 are
incompatible.

Add the weak function mmc_get_env_dev to select the mmc boot instance.
