Rather we can pick one of the regd built from the rules to update to cfg80211 for the whole registered device. We prefer 6 GHz pdev based rules since it has the rules for all bands. If the hw doesn't support 6 GHz, then update rules from one of the pdevs. Also, when regulatory notification is received, update to all the underlying radios/ar so that it becomes aware of the change and as well us it updates its local regd with the new country rules. Later pick the appropriate pdev's regd(6 GHz if available) and apply to cfg80211.
