ati_radeon: Support PCI virtual not eq bus mapping.
Use pci_bus_to_virt() to convert the bus address from the BARs to virtual address' to eliminate the direct mapping requirement. Rename variables to better match usage (_phys -> _bus or no-suffix) This fixes the mpc8572ds CONFIG_PHYS_64BIT mode failure: "videoboot: Video ROM failed to map!" Tested on mpc8572ds with and without CONFIG_PHYS_64BIT. Signed-off-by: Ed Swarthout <Ed.Swarthout@freescale.com>
