x86/PCI: MMCONFIG: trivial is_mmconf_reserved() interface simplification
Since pci_mmcfg_region contains the struct resource, no need to pass the pci_mmcfg_region *and* the resource start/size. Reviewed-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
