TSSI is transmitter signal strength indication, which is a close-loop
hardware circuit to feedback actual transmitting power as a reference for
next transmission.

It does full calibration when we are going to connect an AP. When switching
bands or channels for scanning or some reasons, reset hardware status to
prevent use wrong power value feedback from previous transmission.

It also loads tables of compensation values reflecting current temperature
into registers according to channel and band group to transmit packets
with expected power.
