Subject: [PATCH v2 3/3] x86/cpufeatures: Remove {disabled,required}-features.h
The functionalities of {disabled,required}-features.h are replaced
with the auto-generated header cpufeature_masks.h. Thus they are no
longer needed. So delete them.
None of the macros defined in {disabled,required}-features.h is used
in tools, delete them too.
