Subject: [PATCH v2 2/2] dt-bindings: remoteproc: mediatek: Add optional memory-region to mtk,scp

The SCP co-processor can optionally be passed a reserved memory region
to use. Add this property in the dt-binding.

I left out Angelo's R-b since of the 3 lines in the patch from v1, only
1 is left.

Changes in v2:
- Dropped type and description since it's a well-known property
- Set maxItems to 1
