0ebb2f4159 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.

69f24d1784 MIPS: Optimize current_cpu_type() for better code. 
o Move current_cpu_type() to a separate header file
 o #ifdefing on supported CPU types lets modern GCC know that certain
   code in callers may be discarded ideally turning current_cpu_type() into
   a function returning a constant.
 o Use current_cpu_type() rather than direct access to struct cpuinfo_mips.

475032564e MIPS: Hardwire detection of DSP ASE Rev 2 for systems, as required. 
Most supported systems currently hardwire cpu_has_dsp to 0, so we also
can disable support for cpu_has_dsp2 resulting in a slightly smaller
kernel.
