ath5k: Port to new bitrate/channel API

Browse Source 
Author: Nick Kossifidis <mickflemm@gmail.com>

Tested on 5211, 5213+5112, 5213A+2112A and it wors fine.

Also i figured out a way to process rate vallue found
on status descriptors, it's still buggy but we are getting
closer (i think it improved stability a little).
