[PATCH 01/16] drm/msm/dpu: fix writeback programming for YUV cases

[Abhinav Kumar]

For YUV cases, setting the required format bits was missed
out in the register programming. Lets fix it now in preparation
of adding YUV formats support for writeback.

Fixes: 84a33d0fd921 ("drm/msm/dpu: add dpu_hw_wb abstraction for writeback blocks")
