Update ieee80211_frequency_to_channel from iw

Browse Source 
Make sure the definition of `ieee80211_frequency_to_channel` matches
with the latest changes from iw. Probably not very useful since all
changes seem related to 6GHz / 60GHz / 802.11ah support, which as far
as I can tell create_ap does not yet support.
