disp: msm: dp: issue peripheral flush on every DP commit

Selaa lähdekoodia 
As per DP HPG recommendation, controller flush mode is
set to be synchronous with a vsync. This requires a
peripheral flush to be issued for HDR SDP to be processed.
Currently in a static HDR use case, since the peripheral
flush is not issued after queueing an HDR SDP, it never
gets sent to the sink and it stays in SDR mode. This change
issues a peripheral flush on every DP commit, so that
any pending SDPs are flushed.
