[PATCH v2 08/17] drm/msm/dpu: Drop unused poll_timeout_wr_ptr PINGPONG callback

[Marijn Suijten <marijn.suijten@somainline.org>]

This callback was migrated from downstream when DPU1 was first
introduced to mainline, but never used by any component.  Drop it to
save some lines and unnecessary confusion.
