drm/radeon/kms: allocate vram scratch page on 6xx+ The vram scratch was originally only used on some 7xx asics to work around a hw bug. Allocate the scratch page on all 6xx+ radeons and set the MC_VM_SYSTEM_APERTURE_DEFAULT_ADDR to point to it. We shouldn't ever hit it since we limit the system aperture to vram or vram and AGP, but better safe than sorry.
