fb: pvr2fb: Fix up section mismatch warnings.
A few minor things were broken here. fix and var screeninfo should have been __devinitdata, board_list[] gets renamed to board_driver[] so the modpost matching does the right thing, and we properly discard some of the unused exit sections. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
