    drm/radeon: use cached memory when evicting for vram on non agp

    Force the use of cached memory when evicting from vram on non agp
    hardware. Also force write combine on agp hw. This is to insure
    the minimum cache type change when allocating memory and improving
    memory eviction especialy on pci/pcie hw.
