wireless: remove obsolete chan no/center freq conversion functions
There are a number of functions that shouldn't really be used when modern functions that take the band are available in cfg80211. Remove these, but for now keep * ieee80211_freq_to_dsss_chan and * ieee80211_dsss_chan_to_freq as they're used in older drivers. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
