x86/PCI: MMCONFIG: reject MMCONFIG apertures at address zero

Browse source

Since all MMCONFIG regions go through pci_mmconfig_add(), we can test the
address once there.  If the caller supplies an address of zero, we never
insert it in the pci_mmcfg_config[] table, so no need to test it elsewhere.
