bugzilla: 175542 https://gitee.com/openeuler/kernel/issues/I4DTKU

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=668ca468702e233e33b5fffba5aa11c59c2ee852

--------------------------------

[ Upstream commit 1771a33b ]

"make dtbs_check":

    arm64/boot/dts/renesas/r8a779a0-falcon.dt.yaml: interrupt-controller@f1000000: 'power-domains' does not match any of the regexes: '^(msi-controller|gic-its|interrupt-controller)@[0-9a-f]+$', '^gic-its@', '^interrupt-controller@[0-9a-f]+$', 'pinctrl-[0-9]+'
	    From schema: Documentation/devicetree/bindings/interrupt-controller/arm,gic-v3.yaml

Remove the "power-domains" property, as the GIC on R-Car V3U is
always-on, and not part of a clock domain.
