The endian designation looks good, but it still doesn't explain why you
have a remaining CONFIG_PPC_MPC52xx ifdef encapsulating the property
check in the sm501fb patch. It shouldn't be needed at all. If the
platform supports OF then the property will need to be set one way or the
other, so there is no need for any board or CPU ifdeffery within the
driver itself.
