Subject: [PATCH 1/9] dt-bindings: gpu: mali-bifrost: Don't allow sram-supply by default

The sram-supply is MediaTek-specific, it is and will ever be used
only for the mediatek,mt8183-mali compatible due to the addition of
the mediatek-regulator-coupler driver: change the binding to add
this supply when mediatek,mt8183-mali is present as a compatible
instead of disabling it when not present.

This is done in preparation for adding new bindings for other
MediaTek SoCs, such as MT8192 and others.
