MIPS: pm-cps: Change FSB workaround to CPU blacklist

Browse source

The check for whether a CPU required the FSB flush workaround
previously required every CPU not requiring it to be whitelisted. That
approach does not scale well as new CPUs are introduced so change the
default from a WARN and returning an error to just returning 0. Any CPUs
requiring the workaround can then be added to the blacklist.
