o wl3501: create channel to frequency table and use it in get_freq

This table was obtained from the Planet WAP 1000 Access Point web
interface, accessing it over this driver after I ran nmap against
the AP box that is now only with the wireless interface, i.e. all
accesses to it are over this driver :-)
