drm/radeon: MST support HD7990 with Asus PQ321

Using the latest kernel 4.1.0-rc6, I try to get MST running with
an Asus 4k Display. The Display only show's NoSignal.

Did anyone get a MST display running?


This is the output of dmesg with drm.debug=4 when setting mode to
1920x2160 on both parts of the DP MST output.
