ath5k: Update gain_F calibration code and add documentation
* Update and cleanup rf gain optimization code
* Add comments and refferences to docs and use sane function names
* Use only step index on ath5k_gain, no need to have a pointer to
the current step since we can determine te step from it's index,
this also allows us to put all other structs on rfgain.h and cleanup
ath5k.h a little
* No need for ah_rfgain variable, we use ah_gain.g_state for everything
* Tested on RF2112B chip but gain_F calibration is not yet done
(we will finish this on the next patch where we'll rewrite rf-buffer
handling)
* Use initial rf gain settings for 2316 and 2317 SoCs introduced on a previous patch
It seems big but it's mostly cleanup, very few functional changes have been made on phy.c
