ttm: fix agp since ttm tt rework
ttm tt rework modified the way we allocate and populate the ttm_tt structure, the AGP side was missing some bit to properly work. Fix those and fix radeon and nouveau AGP support. Tested on radeon only so far. Signed-off-by: Jerome Glisse <jglisse@redhat.com> Reviewed-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
