media: platform: mtk-mdp3: Use devicetree phandle to retrieve SCP

Browse source

Instead of walking the entire parent node for something that has the
right compatible, use the scp_get() function provided by the MediaTek
SCP remoteproc driver to retrieve a handle to mtk_scp through the
devicetree "mediatek,scp" (phandle) property.

In case of multi-core SCP, this also allows to select a specific core.
