Include wiphy address setup in wiphy dumps and new wiphy events. The
wiphy permanent address is exposed as ATTR_MAC. If addr_mask is setup,
then it is included as ATTR_MAC_MASK attribute. If multiple addresses
are available, then their are exposed in a nested ATTR_MAC_ADDRS array.
This information is already exposed via sysfs, but it makes sense to
include it in the wiphy dump as well.
