3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alex Deucher <alexander.deuc...@amd.com>
commit b852c985010a77c850b7548d64bbb964ca462b02 upstream.
HW ACR support may have issues on some older chips, so
use SW ACR for now until we've tested further.
