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.
