wifi: Allow configuration of country code for wifi (2/2)

Wifi country code handling is a nightmare - Most retail devices
have region customization in /system for each country a device
is shipped to.

This doesn't work very well for a firmware like Cyanogenmod,
where we try to support all target countries with one firmware
package.  For whatever reason, with newer Broadcom drivers/
firmware blobs, the old trick of using a universal region code
(ccode=ALL in nvram_net.txt) does not seem to work.  Who knows
what the deal is for other wifi chipsets.

The good thing is that wpa_supplicant has a standardized
cross-chipset method for setting the region code, and we
use that here.
