ath5k: Allow user/driver to set txpower
* 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.
