Check whether user has explicitly defined the mmc device to use in mmc_get_env_dev() with CONFIG_SYS_MMC_ENV_DEV.
On STMicroelectronics boards the used mmc device for environment is the instance of boot device provided by the ROM code; the mmc instance is configured by alias in device tree. The used partition is defined in device tree with u-boot,mmc-env-partition = "ssbl".
This patch allows to override this selection for the support of customer boards without alias; for example when SDMMC1 is not used and ENV in mmc0=SDMMC2, user can force the value: CONFIG_SYS_MMC_ENV_DEV = 0.
On STMicroelectronics boards, the current behavior is kept with CONFIG_SYS_MMC_ENV_DEV = -1.
