The DRA7 platforms requires that the dtb used in the SPL really matches the platform to have the best MMC performances. To detect the board type/version an I2C EEPROM is read. This requires that DM is initialized before the detection. As a consequence we must reset the DM after the board detection is a new dtb would better match the platform.
