MIPS: Remove unused R6000 support
The kernel contains a small amount of incomplete code aimed at
supporting old R6000 CPUs. This is:
- Unused, as no machine selects CONFIG_SYS_HAS_CPU_R6000.
- Broken, since there are glaring errors such as r6000_fpu.S moving
the FCSR register to t1, then ignoring it & instead saving t0 into
struct sigcontext...
- A maintenance headache, since it's code that nobody can test which
nevertheless imposes constraints on code which it shares with other
machines.
Remove this incomplete & broken R6000 CPU support in order to clean up
and in preparation for changes which will no longer need to consider
dragging the pretense of R6000 support along with them.
