Use of direct mmc read/write API instead of using the run_command() is not
feasible in this case. As the DFU does read/write to mmc through fat/ext4
files system, uses "fatload/fatwrite" or "ext4load/ext4write" command to
perform read/write to specific partition of mmc device. I think use of
run_command() is more appropriate.
