agp/intel: Rename gtt_bus_addr to gtt_phys_addr
The only use of gtt_bus_addr is as an argument to ioremap(), so it is a CPU physical address, not a bus address. Rename it to gtt_phys_addr to reflect this. No functional change. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch>
