drm/radeon: fix cursor corruption on DCE6 and newer
Jerome Glisse [Mon, 21 Jan 2013 20:50:03 +0000 (15:50 -0500)]
commit e521a29014794d139cca46396d1af8faf1295a26 upstream.

Aruba and newer gpu does not need the avivo cursor work around,
quite the opposite this work around lead to corruption.

agd5f: check DCE6 rather than ARUBA since the issue is DCE
version specific rather than family specific.
