agp/intel: Use pci_bus_address() to get GTTADR bus address
Per the Intel 915G/915GV/... Chipset spec (document number 301467-005), GTTADR is a standard PCI BAR. The PCI core reads GTTADR 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. The spec above only mentions 32-bit GTTADR, but we should still use the standard interface. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch>
