Note these two are specified slightly differently, so return different
values with the same arguments. The ath[59]k version takes the number
of bits (1-based) while the other one takes the position of the high
order bit (0-based). I think the former is a little more natural but
it's a matter of taste.

Anyway I personally have no problem with merging them once the above
is fixed. I wrote a similar patch when I wrote the ath5k version, but
never bothered to submit it.
