rt2x00: Implement tx power temperature compensation
rt2800 devices should adjust their tx power in accordance with the
eeproms temperature calibration values. Add a new driver callback
gain_calibration that is called every 4 seconds.
The rt2800 gain calibration routine simply runs the tx power
configuration that takes care of calculating the temperature
compensation delta.
We don't need to synchronize the calls to rt2800_config_txpower
as they should all happen from mac80211's single threaded workqueue.
