Or we could drop the PRID_IMP_R6000/A check and the final `else' clause
entirely, as we don't even pretend to support the R6k at all anymore, and
this is the final reference remaining. For one we no longer handle the
CPU in `cpu_probe_legacy' so any attempt to boot on such a CPU would
inevitably fail as no CPU options would be set (we probably should have a
`panic' or suchlike as the default case for the switch statement there).
Therefore I'm all for removing this piece instead, complementing commit
3b2db173f012 ("MIPS: Remove unused R6000 support"), where it should have
really happened.
