At sc7280, pingpong block is used to management the dither effects

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
