[PATCH v2 3/3] arm64: dts: mediatek: mt8173: Add domain supply for mfg_async

da9211 regulator needs to be enabled before enabling the mfg_async power
domain. Otherwise the subdomain is not enabled and causes failure in
imgtec gpu driver boot.
Add the "domain-supply" property to the "mfg_async" node in DT.
