From: Stefan Agner <stefan.ag...@toradex.com>
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.
