cfg80211: allow usermode to query wiphy specific regdom
If a wiphy-idx is specified, the kernel will return the wiphy specific
regdomain, if such exists. Otherwise return the global regdom.
When no wiphy-idx is specified, return the global regdomain as well as
all wiphy-specific regulatory domains in the system, via a new nested
list of attributes.
Add a new attribute for each wiphy-specific regdomain, for usermode to
identify it as such.
