drm: rip out drm_core_has_AGP
Most place actually want to just check for dev->agp (most do, but a few don't so this fixes a few potential NULL derefs). The only exception is the agp init code which should check for the AGP driver feature flag. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Dave Airlie <airlied@redhat.com>
