Subject: x86/cpufeatures: Fix various details in the feature definitions

From: Ingo Molnar <mingo@xxxxxxxxxx>

commit f3a624e901c633593156f7b00ca743a6204a29bc upstream.

Kept this commit separate from the re-tabulation changes, to make
the changes easier to review:

 - add better explanation for entries with no explanation
 - fix/enhance the text of some of the entries
 - fix the vertical alignment of some of the feature number definitions
 - fix inconsistent capitalization
 - ... and lots of other small details

i.e. make it all more of a coherent unit, instead of a patchwork of years of additions.
