arm64: dts: fsl-lx2160a: include rev2 chip's dts

The mass production lx2160 rev2 use designware PCIe Controller. Old Rev1
which use mobivel PCIe controller was not supported. 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 in dtb. Change freescale's board to use rev2's dtsi firstly.
