x86/cpuid: replace magic number with named constant
CPUID leaf Fn8000_0001.EDX contains a copy of many Fn0000_0001.EDX bits. Define a name for this mask to improve readability and avoid typos. Signed-off-by: Andre Przywara <andre.przywara@amd.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
