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.
