Subject: [PATCH 3.16.y-ckt 077/126] drm/radeon: make some dpm errors debug only

3.16.7-ckt22 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alex Deucher <alexander.deucher@....com>

commit 9c565e3386fdc804a61f8c116efc2c5999ba46e1 upstream.

"Could not force DPM to low", etc. is usually harmless and
just confuses users.
