[0/2] MediaTek MDP3: use devicetree to retrieve SCP

Message

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.

This series no longer applies to our staging master branch.

Since Krzysztof also asked for a better patch 1/2, I prefer a rebased and
updated v5.
