cfg80211: Extend channel to frequency mapping for 802.11j
Extend channel to frequency mapping for 802.11j Japan 4.9GHz band, according to IEEE802.11 section and Annex J. Because there are now overlapping channel numbers in the 2GHz and 5GHz band we can't map from channel to frequency without knowing the band. This is no problem as in most contexts we know the band. In places where we don't know the band (and WEXT compatibility) we assume the 2GHz band for channels below 14. This patch does not implement all channel to frequency mappings defined in 802.11, it's just an extension for 802.11j 20MHz channels. 5MHz and 10MHz channels as well as 802.11y channels have been omitted. The following drivers have been updated to reflect the API changes: iwl-3945, iwl-agn, iwmc3200wifi, libertas, mwl8k, rt2x00, wl1251, wl12xx. The drivers have been compile-tested only.
