Aravind Gopalakrishnan fb53a1ab88 x86/quirks: Add workaround for AMD F16h Erratum792 
The workaround for this Erratum is included in AGESA. But BIOSes
spun only after Jan2014 will have the fix (atleast server
versions of the chip). The erratum affects both embedded and
server platforms and since we cannot say with certainity that
ALL BIOSes on systems out in the field will have the fix, we
should probably insulate ourselves in case BIOS does not do the
right thing or someone is using old BIOSes.

Refer to Revision Guide for AMD F16h models 00h-0fh, document 51810
Rev. 3.04, November2013 for details on the Erratum.

Tested the patch on Fam16h server platform and it works fine.
