[1/2] drm/msm/dpu: Drop enable and frame_count parameters from dpu_hw_setup_misr()
Commit Message
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.
Fixes: 7b37523fb1d1 ("drm/msm/dpu: Move MISR methods to dpu_hw_util")

No need for the Fixes tag, there was no issue in that (or the previous) commits
