drm/radeon/kms: remove rs4xx gart limit
We used to limit the rs4xx gart aperture to 32 MB, but I suspect that was due to not meeting the alignment requirements of the aperture. This patch should only be applied after: "drm/radeon/kms: fix gtt MC base alignment on rs4xx/rs690/rs740 asics" has been applied. This patch should probably soak for a bit in d-r-t.
