drm/msm/dpu: Drop enable and frame_count parameters from dpu_hw_setup_misr()
[ Upstream commit 3313c23f3eab698bc6b904520ee608fc0f7b03d0 ]
Drop the enable and frame_count parameters from dpu_hw_setup_misr() as they
are always set to the same values.
In addition, replace MISR_FRAME_COUNT_MASK with MISR_FRAME_COUNT as
frame_count is always set to the same value.
