If a device uses the default EEPROM code, typically only the main CTLs are valid, and they do not apply properly when switching to a different regulatory domain. If the regdomain deviates from the EEPROM one, force the world roaming regdomain to ensure that power limits are sane Signed-off-by: Felix Fietkau <nbd@nbd.name>
