Subject: [PATCH 1/6] dt-bindings: power: mediatek: Add another nested power-domain layer

The MT8188 SoC has a more in-depth power-domain tree, and the
CHECK_DTBS=y check could fail because the current MediaTek power
dt-binding is insufficient to cover its CAM_SUBA and CAM_SUBB
sub-domains.

Add one more nested power-domain layer to pass the check.
