Stephen Dickey ef152a1111 sched/walt: limit frequency on thermal halted cpus 
Tasks affined to a single cpu will be allowed to run on that
cpu regardless of the halt state of the cpu. This creates
an issue for thermally mitigated cpus that are also halted
by cooling devices.

Limit cpus to fmin that are halted by a thermal client only.
Since tasks can run on a halted cpu under some circumstances,
for example, if they've been affined to only one cpu, the
performance of a task affined to a single cpu should not
be reduced simply because the cpu is currently halted.
Therefore, only thermally induced halt shall cause the
frequency limit.

When a cpu is halted by a thermal client, changing the cpu's
frequency at the next update is critical to actually mitigate the
cpu's temperature. When the cpu is unhalted for thermal
reasons, the frequency requested by the cpu should be
restored just as quickly.

Thermal cooling devices can mitigate groups of cpus or
individual cpus, per the logic of the thermal drivers.
Since this cpu's frequency is tied to that of the other
cpus in the system, the frequency shall be limited for
every cpu in the cluster.
