3.11.10.1 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Alex Deucher <alexander.deucher at amd.com>
commit 958b84fb3bef193198538b5c5902fa687cc8363f upstream.
Adjust some of the TN dpm settings for stability. Enabling
these features causes hangs and other stability problems
on certain boards.
v2: leave uvd dpm enabled
