video/msm: HACK to correct lcdc/mdp clocks ref counts

Originally committed by jcsullins on Mar 10, 2013
This corrects the reference counts for the pixel_lcdc, pixel_mdp
and mdp clocks. These clocks have incorrect reference counts due
to msm_clock_fixup in board-tenderloin. These clocks having incorrect
reference counts caused them to never be turned off and thus added
about 25-30 mA extra drain during sleep.
