drm/radeon/kms/DCE4.1: fix Select_CrtcSource EncodeMode setting for DP bridges (v2)
Settings in this table reflect the physical panel/connector rather than the internal dig encoding. v2: fix typo for DRM_MODE_CONNECTOR_VGA case. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
