ath5k: Allow user/driver to set txpower

Browse source 
* Now that we have regulatory control enable the driver to set
 txpower on hw

 * Also use txpower table offset so that we can match
 power range set by user/driver with indices on power table.

 Tested 2 different cards (a CM9 and an RF5112-based ubnt) and got
 the same output using a remote machine to measure per-packet rssi
 (conected the cards using attenuators). I also switched between
 various tx power levels and i saw an equal power change on the remote
 machine (so txpower changes as expected) and verified that we have
 the same output on each rate.
