This is useful when the tools used to manage the wifi interface do not
support setting the regdomain (e.g. NetworkManager). As long as the
country code is not set in configuration the init script does not
change anything.

If this doesn't seem relevant for Buildroot please let me know, I'll
move it to a local package then. On the other hand, if it's merged I
could create a follow-up to allow setting the initial regdomain in the
config file from the Buildroot config.
