[Freedreno] [PATCH 1/3] drm/msm/dpu: Drop unused members from HW structs

[Marijn Suijten]

Some of these members were initialized while never read, while others
were not even assigned any value at all.  Drop them to save some space,
and above all confusion when looking at these members.

Fixes: 25fdd5933e4c ("drm/msm: Add SDM845 DPU support")
Fixes: 84a33d0fd921 ("drm/msm/dpu: add dpu_hw_wb abstraction for writeback blocks")
