ppc32: Resurrect Documentation/powerpc/cpu_features.txt

Hi,

Documentation/powerpc/cpu_features.txt mysteriously disappeared sometime when 2.5 forked off.

Searching through BK logs on linux.bkbits.net didn't reveal anything, unfortunately. The only reference I could pick up from searching the available lkml archives is the 2.4.20-pre11 ChangeLog where this was first merged.

Thus far, nothing indicates it was intentionally removed, and AFAICS, is still up to date with the current code.

Against 2.6.9. Applies cleanly against 2.6.10-rc3. Thanks.
