fb: pvr2fb: Fix up section mismatch warnings.

Browse Source 
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.
