[PATCH] dt-bindings: remoteproc: mtk,scp: Allow multiple memory regions

[Arnab Layek]

Update the memory-region property to support 1-2 reserved memory
regions instead of exactly one. This is needed for newer MediaTek
SoCs like MT8188 which require additional memory regions for SCP
operation.

Tested on MT8188 Geralt platform.
