Subject: [PATCH v4 01/12] dt-bindings: gpu: mali-bifrost: Split out MediaTek power-domains variation

In preparation for adding new bindings for new MediaTek SoCs, split out
the power-domains variation from the `else` in the current
mediatek,mt8183-mali conditional.

The sram-supply part is left in place to be disallowed for anything
that is not compatible with "mediatek,mt8183-mali" as this regulator
is MediaTek-specific and it is, and will ever be, used only for this
specific string due to the addition of the mediatek-regulator-coupler
driver.
