cfg80211: adapt to new channelization of the 6GHz band
The 6GHz band does not have regulatory approval yet, but things are moving forward. However, that has led to a change in the channelization of the 6GHz band which has been accepted in the 11ax specification. It also fixes a missing MHZ_TO_KHZ() macro for 6GHz channels while at it. This change is primarily thrown in to discuss how to deal with it. I noticed ath11k adding 6G support with old channelization and ditto for iw. It probably involves changes in hostapd as well.
