[PATCHv2 1/2] PCI: layerscape: Add support for ls2088a

[Zhiqiang Hou <Zhiqiang.Hou@nxp.com>]

From: Hou Zhiqiang <Zhiqiang.Hou@nxp.com>

The ls2088a pcie controller's some registers address are different
from ls2080a, so add a match entry to identify ls2088a pcie.

V2:
 - Removed "fsl,ls1088a-pcie" from the layerscape-pci binding doc.
