[patch] use channel if no frequency sent

[Holger Schurig]

My driver doesn't send a frequency, but a channel when scanning access 
points with "iwlist eth1 scan". iwlist displays this correctly.

This patch adds a local frequency table and converts the channel. 
driver_broadcom also has this frequency table, but for now I kept it 
local.


After I got the right frequency, I called wpa_driver_wext_set_freq() from 
my driver_hermes.c and then I finally got an association event:
