toradex: configblock: initialize MMC before switching partition
If the module is in serial downloader mode, we do no longer read the environment from eMMC. Therefor, the eMMC is unitialized when trying to read the config block. Use mmc_init to initialize the selected MMC device before using it. Note: In case the MMC has already been initialized, the mmc_init detects that and returns immediately.
