[PATCH] x86, amd: Remove superfluous CPU family/model check

[PATCH] x86, amd: Remove superfluous CPU family/model check

[Andreas Herrmann]

From: Andreas Herrmann <andreas.herrmann3@amd.com>

amd_fixup_dcm() already checks for existence of a CPUID flag, so there
is no point in further restricting this function to run only on
specific CPUs.

In particular this prevents amd_fixup_dcm() to be executed on future
AMD CPU families which might also be available as multi-node
processors. (IMHO this is good reason to tag this patch for stable
trees.)
