A P2P_DEVICE netdev is (always) created by the supplicant if the driver
advertises support for it, and then p2p-device operations are done there
rather than on the wlan0 netdev.
The driver has to support it (interface combinations) and then deal with
add_interface for it. You can see mac80211 with hwsim and iwlmvm for
example.
