Unfortunately with this change we now are unable to do FS mode boots
from MMC1 as with the way the code works today we will always load and
assume that the hard-coded raw location contains U-Boot.  Further, we
cannot fix this by just changing other logic to try FS-then-RAW as it
would also make us have to ignore what order the ROM is telling us to
try.

This reverts commit 22d90d56
