Subject: [PATCH 7/8] arm64: dts: allwinner: a64: add SCPI power domain support

The SCPI protocol allows controlling device power domains, which
abstracts the various ways of providing voltage to devices like Ethernet
PHYs or on-board WiFi chips.
Provide the power domain provider DT node, which can be referenced by
a power domain consumer device.
