It can't fallback to fsl,ls2088a-pcie if fsl,lx2160a-pcie exist, which are
totally imcompatible between fsl,ls2088a-pcie and fsl,lx2160a-pcie.

Previous dtb can work just because uboot dynamtic change fsl,lx2160a-pcie
to fsl,ls2088a-pcie when boot kernel.

fsl,lx2160a-pcie should be removed because Rev1 have not mass productioned.
