Subject: [PATCH] sfc: Convert firmware subtypes to native byte order in
 efx_mcdi_get_board_cfg()

commit bfeed902946a31692e7a24ed355b6d13ac37d014 upstream.

On big-endian systems the MTD partition names currently have mangled
subtype numbers and are not recognised by the firmware update tool
(sfupdate).
