arm64: dts: allwinner: a523: enable Mali GPU for all boards

All devices based on the A523/A527/H728/T527 processors contain a G57 MC1 GPU.

Enable the DT nodes for this GPU and specify a regulator that supplies power
to the SoC's VDD_GPU pins. The other parameters are set in the SoC dtsi,
so are board independent.
