Subject: [PATCH v3 10/20] drm/dp: Always print aux channel name in logs

Since we're about to convert everything in drm_dp_helper.c over to using
drm_dbg_*(), let's also make our logging more consistent in drm_dp_helper.c
while we're at it to ensure that we always print the name of the AUX
channel in question.
