arm64: dts: allwinner: a523: add Mali GPU node

The Allwinner A523 SoC features the Mali-G57 MC1 GPU, which belongs
to the Mali Valhall (v9) family. There is a power domain specifically
for this GPU that needs to be enabled to utilize it.

To enable in a specific device, we need to enable the gpu node and specify
the “mali-supply” regulator additionally in the device tree.
