[PATCH] MIPS: IP27: Update/restructure CPU overrides

[Joshua Kinard <kumba@gentoo.org>]

From: Joshua Kinard <kumba@gentoo.org>

Inspired by Maciej's recent patch to update DEC cpu-feature-overrides.h,
I updated IP27's as well to disable features known to not apply to the
IP27 platform or the R10K-series of CPUs.

Before:
   text    data     bss     dec     hex filename
8616648  463200  472240 9552088  91c0d8 vmlinux

After:
   text    data     bss     dec     hex filename
8592256  471392  472240 9535888  918190 vmlinux

I believe the increase in the size of the data section is for the same
reasons as in the DEC patch.

The number of changes is due to restructuring the file to be similar to
IP30's, so that eventually, all of the SGI platforms will have a similar
look to their cpu-feature-overrides.h file, making it easier to update
in the future.  I'll also send one for IP32 shortly, as that needs some
more careful updating due to the various CPUs it supports.
