Subject: 1. Fix a UEFI errata to add UINT32 Reserved field in
 MEDIA_RELATIVE_OFFSET_RANGE_DEVICE_PATH to ensure all field are natural
 aligned. This is non-backward compatibility in binary level. 2. Swap the
 order of MEDIA_FW_VOL_FILEPATH_DEVICE_PATH and MEDIA_FW_VOL_DEVICE_PATH with
 the UEFI spec update.
