PCI: Add MCFG quirks for X-Gene host controller
PCIe controllers in X-Gene SoCs are not ECAM compliant: software needs to
configure additional controller's register to address device at
bus:dev:function.
Add a quirk to discover controller MMIO register space and configure
controller registers to select and address the target secondary device.
The quirk will only be applied for X-Gene PCIe MCFG table with
OEM revison 1, 2, 3 or 4 (PCIe controller v1 and v2 on X-Gene SoCs).
