mec: Correct the access mode for short payloads

If the Host Command payload is less than 4 bytes
    and is word aligned then the payload was not transferred at all.
    EC reads the old packet and CRC mismatch occurs.

In this issue, the HC command packet
    consisting of EC_CMD_REBOOT_EC as command and EC_REBOOT_COLD
    as payload encountered the same problem as above.
    Hence select byte access mode for shorter payloads.

    TEST=System should boot after
    chromeos-firmwareupdate
