[PATCH] drm/scdc-helper: Convert errors into debug messages

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Since we may attempt to reconfigure SCDC when the sink has already been
disconnected we probably shouldn't scare the user with errors in dmesg
that are 100% expected in that case. Just leave it up to the caller
whether to print an error message or not, and just output debug
messages from the helper itself.
