ath5k: Extend rate_duration

Browse Source 
* Extend ieee80211_generic_frame_duration to support the various
 bwmodes.

 * Better document what's going on with ack bitrates and update
 write_rate_duration to support the standard ack bitrates (when
 we don't set the high bit).

 * Get rid of set_ack_bitrate_high and introduce a flag on ath5k_hw
 for this (we only called the function on init anyway so there is no
 difference).
