Subject: [PATCH] dt-bindings: ata: rockchip-dwc-ahci: add missing power-domains

The Rockchip variant of the dwc-ahci controller does have and need power-
domains to work, though the binding does not mention them, making dtccheck
quite unhappy:

  DTC_CHK arch/arm64/boot/dts/rockchip/rk3568-odroid-m1.dtb
/home/devel/hstuebner/00_git-repos/linux-rockchip/_build-arm64/arch/arm64/boot/dts/rockchip/rk3568-odroid-m1.dtb: sata@...00000: Unevaluated properties are not allowed ('power-domains' was unexpected)
        from schema $id: http://devicetree.org/schemas/ata/rockchip,dwc-ahci.yaml#

Fix that by adding the missing power-domain property to the binding.
