wireless: Add channel/frequency conversions to ieee80211.h
Added mappings for FHSS, DSSS and OFDM channels - with macros to point HR DSSS and ERP to the DSSS mappings. Currently just static inline functions. Use the new functions in the older fullmac drivers. This eliminates a number of const static buffers and removes a couple of range checks that are now redundant.
