drm/radeon/mst: fix regression in lane/link handling.
The function this used changed in
092c96a8ab9d1bd60ada2ed385cc364ce084180e
drm/radeon: fix dp link rate selection (v2)
However for MST we should just always train to the
max link/rate. Though we probably need to limit this
for future hw, in theory radeon won't support it.
This fixes my 30" monitor with MST enabled.
