ath5k: Extend rate_duration
* 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).
