Subject: [PATCH v2 1/6] dt-bindings: clock: mediatek: Add power-domains
 property

The mt8183-mfgcfg node uses a power domain in its device tree node.
To prevent schema validation warnings, add the optional `power-domains`
property to the binding schema for mediatek syscon clocks.

Fixes: 1781f2c46180 ("arm64: dts: mediatek: mt8183: Add power-domains property to mfgcfg")
