drm/radeon/kms: rewrite DP handling
- reorganize the functions based on use - clean up function naming - rework link training to better match what we use internally - add initial support for DP 1.2 (no MST yet) Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
