[PATCH 1/2] x86, powernow-k8: Fixup missing _PSS objects message

[Borislav Petkov <bp@amd64.org>]

From: Borislav Petkov <borislav.petkov@amd.com>

_PSS objects can also be missing if Cool'N'Quiet is disabled in the
BIOS. Add that to the FW_BUG message for the user to try before updating
her BIOS. Fix formatting.
