[1/2] drm/amd/amdgpu_dm/mst: Remove useless sideband tracing

Commit Message

Lyude Paul March 31, 2020, 9:22 p.m. UTC

We already trace DPCD reads/writes on both MST and SST, there's no
reason to have this code here (plus, toggling these things with a
define at the top of the file isn't how we do things in the kernel).
