cpufreq: Retain only online cpus in managed_policy->cpus

cpufreq's handling of cpu online event can incorrectly initialize
managed_policy->cpus to include offline cpus. This causes cpufreq
governors to include offline cpus in their idle time computation, which
causes frequency to shoot up beyond normal levels (on systems where 2 or
more cpus need to be synchronized wrt frequency change).

This frequency shootup was not seen prior to commit 21111be8 which
changed idle time accounting for offline cpus. Prior to commit 21111be8,
idle time statistics for offline cpus would include their offline time
as well. Post commit 21111be8, offline time is not included in a cpu's
idle time statistics.

As a result, ondemand (or other cpufreq) governors would see unchanged
idle time for offline cpus, causing them to interpret those (offline)
cpus as 100% busy, which is wrong.

This patch fixes the issue by modifying cpufreq's hotplug handling to
retain only online cpus in managed_policy->cpus field. cpufreq governors
would then skip such offline cpus from idle time calculations.

drivers: thermal: properly limit CPU frequency when the temperature is too hot: if we throttle too much games will lag so we'll only scale down to 1026MHz until the device cools down, then back to 1512MHz again. Added other smaller routine changes to make it work properly.

thermal: tsens8960: Increase the polling rate

Change the polling rate at which the sensors temperature
is read from 1 second to .25 seconds. On faster parts
there is a need to poll the temperature at a higher
frequency to improve reporting temperature changes.
