PCI: layerscape: Add "fsl,ls2085a-pcie" compatible ID

commit dbae40b76abef2f8a7e7bf1701f77df9e73def48 upstream.

The Layerscape PCI host driver must recognize ls2085a compatible when using
firmware with ls2085a compatible property, otherwise the PCI bus won't be
detected even though ls2085a compatible is included by the dts.
