From: Richard Zhu <hongxing.zhu at nxp.com>

Add i.MX8Q PCIe "fsl,imx8q-pcie" compatible strings.

Add "fsl,local-address" property for i.MX8Q platforms. fsl,local-address
is address of PCIe module in high speed io (HSIO)subsystem bus fabric. HSIO
bus fabric convert the incoming address base to this local-address. Two
instances of PCI have difference local address.
