Instead of aborting country code setup in firmware, use ISO3166 country
code and 0 rev as fallback, when country_codes mapping table is not
configured. This fallback saves the country_codes table setup for recent
brcmfmac chipsets/firmwares, which just use ISO3166 code and require no
revision number.
