x86, microcode: Correct microcode revision format

506ed6b ("x86, intel: Output microcode revision in /proc/cpuinfo") added microcode revision format to /proc/cpuinfo and the MCE handler in decimal format but both AMD and Intel patch levels are handled as hex numbers. Fix it. Acked-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
