Feature request: Display available channels based on country

[caeci11ius]

I've recently noticed that we don't seem to get a list of available channels based on the country settings. I've set country to 'AU' in the settings file, and "iw reg get" returns the following:

country AU:
(2402 - 2482 @ 40), (N/A, 20)
(5170 - 5250 @ 40), (3, 23)
(5250 - 5330 @ 40), (3, 23), DFS
(5735 - 5835 @ 40), (3, 30)

I should be able to get channels up to 13, but only 11 and below appear in the list. If it's not too much effort, it'd be nice if the channels displayed in the list corresponded to the set country code, even if we don't initially get an option in the GUI to set this...
