ArmVirtualizationPkg/PciHostBridgeDxe: ECAM enables 4KB config space

The Enhanced Configuration Access Mechanism provides access to 4096
register bytes per PCIe B/D/F. The MAX_PCI_REG_ADDRESS macro that we're
changing here is used by RootBridgeIoCheckParameter() for verifying config
space boundaries in EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL.Pci.Read() and
.Write().
