Subject: [PATCH 1/2] arm64: dts: mediatek: mt8195-cherry: Add MFG0 domain supply
MFG0 is the main power domain for the GPU and its surrounding glue
logic, and has a specific power rail.
Add its power supply on Cherry platforms and remove the now useless
(and wrong) regulator-always-on property from the vbuck1 regulator.
