Subject: [PATCH v2 09/16] arm64: dts: mediatek: mt8192-asurada: Add MFG0 domain supply

From: Nícolas F. R. A. Prado <nfraprado@...labora.com>

The mfg0 power domain encompasses the whole GPU and its surrounding
glue logic. This power domain has a separate power rail.

Add its power supply for Asurada.
