x86/PCI: MMCONFIG: add resource to struct pci_mmcfg_region
This patch adds a resource and corresponding name to the MMCONFIG structure. This makes allocation simpler (we can allocate the resource and name at the same time we allocate the pci_mmcfg_region), and gives us a way to hang onto the resource after inserting it. This will be needed so we can release and free it when hot-removing a host bridge.
