Imre Deak 2b82435cb9 drm/i915/dp_mst: Fix enabling pipe clock for all streams 
commit afb2c4437d ("drm/i915/ddi: Push pipe clock enabling to encoders")
inadvertently stopped enabling the pipe clock for any DP-MST stream
after the first one. It also rearranged the pipe clock enabling wrt.
initial MST payload allocation step (which may or may not be a
problem, but it's contrary to the spec.).

Fix things by making the above commit truly a non-functional change.
