ath5k: Make some changes to follow register dumps.

Make some changes which mimic what we see in register dumps.
This patch does not add a helper to ath5k_hw_reset(). It
does seem clear we need a re-shuffle around ath5k_hw_reset()
though as code in there is lengthy and already hitting 80-char
limit. This can be dealt with later though.
