No (active) developer owns this hardware, so let's remove Linux support.

Clean up cpu-feature-overrides, which only repeat the default.

The cpu_has_local_ebase macro is, confusingly, not used to indicate
whether the EBase register is local to a CPU or not. Instead it
indicates whether we want to generate the TLB refill exception vector
each time a CPU is brought online. Doing this makes little sense on any
system, since we always use the same value for EBase & thus we cannot
have different TLB refill exception handlers per CPU.
Regenerating the code is not only pointless but also can be actively
harmful, as commit 8759934e2b6b ("MIPS: Build uasm-generated code only
once to avoid CPU Hotplug problem") described. That commit introduced
cpu_has_local_ebase to disable the handler regeneration for Loongson
machines, but this is by no means a Loongson-specific problem.
Remove cpu_has_local_ebase & simply generate the TLB refill handler once
during boot, just like the rest of the TLB exception handlers.

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.

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.

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.
