Changes in v2: - Rebased over media_stage master as of 05/10/2023 - Reworked description of mediatek,scp property in bindings - Dropped Conor's and Chen-Yu's R-b tags from bindings patch due to the description rework. Especially now that Multi-Core SCP support has landed, it makes sense to retrieve the SCP handle by using the "mediatek,scp" property (as already done in MediaTek VCODEC), both to select one specific SCP core for MDP3 and to avoid walking the parent node to find a SCP node.
