MIPS16e2: Provide feature overrides for non-MIPS16 systems
...
Hardcode the absence of the MIPS16e2 ASE for all the systems that do so
for the MIPS16 ASE already, providing for code to be optimized away.

MIPS: DEC: Update CPU overrides
...
Update CPU overrides for the DEC port with the recent additions, shaving
off some effectively dead code:
text data bss dec hex filename
5586952 233132 5990368 11810452 b43694 vmlinux.32-old
5581248 233140 5990368 11804756 b42054 vmlinux.32-new
text data bss dec hex filename
6036936 356648 10756544 17150128 105b0b0 vmlinux.64-old
6029896 360752 10756544 17147192 105a538 vmlinux.64-new
The data size increase is due to the special alignment requirement of
`init_thread_union' aka `.data..init_task' moving it up to the nearest
page boundary and making the amount of padding at its front rely on how
far within a page text ends.

MIPS: Correct `nofpu' non-functionality
...
The `cpu_has_fpu' feature flag must not be hardcoded to 1 or the `nofpu'
kernel option will be ignored. Remove any such overrides and add a
cautionary note. Hardcoding to 0 is fine for FPU-less platforms.

MIPS: Create a common <asm/mach-generic/war.h>
...
11 platforms require at least one of these workarounds to be enabled; 22
platforms do not. In the latter case we can fall back to a generic version.
Note that this also deletes an orphaned reference to RM9000_CDEX_SMP_WAR.
