drm/i915: s/intel_dp_sink_dpms/intel_dp_set_power/

Browse Source 
commit 0e634efd858e0e9331ea037e1a142e34a446e9e3 upstream.

Rename intel_dp_sink_dpms() to intel_dp_set_power()
so one doesn't always have to convert from the DPMS
enum values to the actual DP D-states.

Also when dealing with a branch device this has nothing to
do with any sink, so the old name was nonsense anyway.
Also adjust the debug message accordingly, and pimp it
with the standard encoder id+name thing.

Trivial bits done with cocci:
