This enables the capability to enable cellular base station
regulatory hint support to ath5k, ath9k, ath9k_htc and carl9170.

Sending as RFC given that I'd like review from Sujith and
Christian on the firmware side of things on ath9k_htc
and carl9170. I am pretty certain both allow us to do
all regulatory control on the driver and becuase of this
we should be able to support this feature, however I'd
like to be sure. Other drivers that have this regulatory
control in firmware require quite a bit of testing /
synching, as with ath6kl -- but we should be fine here.
We don't enable this by default as we don't want all
Linux distributions to be enabling CFG80211_CERTIFICATION_ONUS
sporadically, instead this must be done by system integrators
on case by case basis only when they are targeting supporting
and testing these features.
