mac80211: ath10k: Allow to enable the thermal code of ath10k

Some ath10k firmware versions allow to access the chip internal a
temperature sensor and allow to reduce the amount of the time when the card
is allowed to send. The latter is required on devices which tend to
overheat.

An userspace service has to read
/sys/class/ieee80211/phy*/device/hwmon/hwmon*/temp1_input regularly and
then decide how much the device has to be throttled. This can be done by
writing to /sys/class/ieee80211/phy*/device/cooling_device/cur_state. By
default it is not throttled (0) but it can be throttled up to 100(%).
