Changes in v2:
- rewrite commit message - requested by Krzysztof

The commit 8ac47837f0e0 ("arm64: dts: zynqmp: Add missing iommu IDs") and
the commit 959b86ae37c6 ("arm64: dts: xilinx: Add the power nodes for
zynqmp") described these properties long time ago in Linux that's why the
patch is also fixing dts_check warnings.
