[RFC v3 1/5] dt-bindings: Add a binding for Mediatek SCP

[Pi-Hsun Shih]

From: Erin Lo <erin.lo@xxxxxxxxxxxx>

Add a DT binding documentation of SCP for the
MT8183 SoC from Mediatek.

Signed-off-by: Erin Lo <erin.lo@xxxxxxxxxxxx>

Changes from v2:
 - No change. I realized that for this patch series, there's no need to
   add anything under the mt8183-scp node (neither the mt8183-rpmsg or
   the cros-ec-rpmsg) for them to work, since mt8183-rpmsg is added
   directly as a rproc_subdev by code, and cros-ec-rpmsg is dynamically
   created by SCP name service.

Changes from v1:
 - No change.
