agp: Support 64-bit APBASE Per the AGP 3.0 spec, APBASE is a standard PCI BAR and may be either 32 bits or 64 bits wide. Many drivers read APBASE directly, but they only handled 32-bit BARs. The PCI core reads APBASE at enumeration-time. Use pci_bus_address() instead of reading it again in the driver. This works correctly for both 32-bit and 64-bit BARs.
