cfg80211: Allow for strict regulatory settings
This allows drivers to request strict regulatory settings to be applied to its devices. This is desirable for devices where proper calibration and compliance can only be gauranteed for for the device's programmed regulatory domain. Regulatory domain settings will be ignored until the device's own regulatory domain is properly configured. If no regulatory domain is received only the world regulatory domain will be applied -- if OLD_REG (default to "US") is not enabled. If OLD_REG behaviour is not acceptable to drivers they must update their wiphy with a custom reuglatory prior to wiphy registration. Signed-off-by: Luis R.
