[PATCH v3 1/2] dt-bindings: remoteproc: mediatek: Make l1tcm reg optional for mtk, scp

[Nícolas F. R. A. Prado]

The SCP has three memory regions: sram, cfg and l1tcm. While the first
two are required, l1tcm is optional. Fix the dt-binding so that it can
be omitted and update the description. This gets rid of dtbs_check
warnings for devicetrees where the l1tcm reg is missing like mt8183.

Changes in v3:
- Made the cfg reg required again. After looking again into the mtk-scp
  driver, only l1tcm is optional.
- Added mention that a dtbs_check warning gets fixed by patch in commit
  message.
