WiFi region always "world" even when specified otherwise in wpa_supplicant.conf

The WiFi region on MiSTer seems to always be "world", even if it's set to TW or US or anything else in wpa_supplicant.conf.

As a result, I can't see my 5 GHz access point when it's set to certain US-specific channels, even when wpa_supplicant.conf is set to US. Being set to world may also limit the transmit power of the USB dongle, but this is a less critical issue.

Talking with @birdybro in the channel, we think that we need CRDA to be able to set the WiFi region correctly. Can we add it?

Symptoms:

• Run iw reg get on any MiSTer and you get this:

# iw reg get
global
country 00: DFS-UNSET

• As a result the region being set to world, MiSTer won't ever see or connect to APs on certain region-specific channels even if wpa_supplicant.conf is configured correctly.
