Subject: [PATCH 1/4] drm/msm/dpu: remove DSC feature bit for PINGPONG on
 MSM8937

The MSM8937 platform doesn't have DSC blocks nor does have it DSC
registers in the PINGPONG block. Drop the DPU_PINGPONG_DSC feature bit
from the PINGPONG's feature mask and, as it is the only remaining bit,
drop the .features assignment completely.

Fixes: c079680bb0fa ("drm/msm/dpu: Add support for MSM8937")
