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_PYS_64BIT mode failure: "videoboot: Vidoe ROM failed to map!"
Tested on mpc8572ds with and without CONFIG_PHYS_64BIT.

This patch is independent of the ati radeon return error patch, but for ease of debug it should be applied with this one.
