drm/msm/disp/dpu: fix sc7280_pp base offset
[ Upstream commit ce68153edb5b36ddf87a19ed5a85131498690bbf ]
At sc7280, pingpong block is used to management the dither effects
to reduce distortion at panel. Currently pingpong-0 base offset is
wrongly set at 0x59000. This mistake will not cause system to crash.
However it will make dither not work. This patch correct sc7280 ping
pong-0 block base offset.
Changes in v2:
-- add more details info n regrading of pingpong block at commit text
