[paul-pl.chen <paul-pl.chen@mediatek.com>]

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.

+description:
+  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.

+properties:
+  compatible:
+    const: mediatek,mt8196-outproc

+  reg:
+    maxItems: 1

+
+  interrupts:
+    maxItems: 1

+  - compatible
+  - reg
+  - clocks
