MIPS: IP27: Update/restructure CPU overrides
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.
