drm/radeon: add some additional 6xx/7xx/EG register init
- SMX_SAR_CTL0 needs to be programmed correctly to prevent problems with memory exports in certain cases. - VC_ENHANCE needs to be initialized on 6xx/7xx. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org Signed-off-by: Dave Airlie <airlied@redhat.com>
