[PATCH] x86_64: AMD Family 10h enable ext config in quirk

[Yinghai Lu]

need to be applied after
gregkh-pci-pci-make-pci-extended-config-space-a-driver-opt-in.patch
x86_64-set-cfg_size-for-amd-family-10h-in-case-mmconfig-is-used.patch

[PATCH] x86_64: AMD Family 10h enable ext config in quirk

because of changes of
gregkh-pci-pci-make-pci-extended-config-space-a-driver-opt-in.patch

need to call pci_enable_ext_config to enable mmconfig before set right cfg_size
even MCFG is there
