Subject: [PATCH 2/3] arm64: dts: fsl-lx2160a: add rev2 support
Add rev2 dtsi. Although uboot fixup can change compatible string
fsl,lx2160a-pcie to fsl,ls2088a-pcie since 2019, it is quite confused and
should correctly reflect hardware status. So add fsl-lx2160a-rev2.dtsi to
overwrite pcie's compatible string.
Add PCIe EP nodes.
