[PATCH 7/13] d80211: add a perm_addr hardware property

[Johannes Berg <johannes@sipsolutions.net>]

After removing knowledge of the master net_dev from drivers,
they'll still need a way to tell us which MAC address they have.
This is that way, the perm_addr is initially used for all devices.

resend with the wiphy thing fixed. not sure how that slipped in
