From: Paul-pl Chen <paul-pl.chen@mediatek.com>

Add mediate,outproc.yaml to support OUTPROC for MT8196.
MediaTek display overlap output processor, namely OVL_OUTPROC
or OUTPROC,handles the post-stage of pixel processing in the
overlapping procedure.

+ MediaTek display overlap output processor, namely OVL_OUTPROC or OUTPROC,
+ handles the post-stage of pixel processing in the overlapping procedure.
+ OVL_OUTPROC manages pixels for gamma correction and ensures that pixel
+ values are within the correct range.
