wifi: cfg80211: restrict cfg80211_chandef_create() to only HT-based bands

cfg80211_chandef_create() should only be used by bands that are
HT-based and the chantype argument makes sense. Insert a WARN such
that it isn't used on 60GHz and S1GHz bands and to catch any
potential existing uses by those bands.
