P2P: Adding option to manage device drivers creating random MAC addresses

Browse source 
Add option 2 to the p2p_device_random_mac_addr configuration option to
support device drivers which use by default random MAC adresses when
creating a new P2P Device interface (for instance, the BCM2711 80211
wireless device driver included in Raspberry Pi 4 Model B). In such
case, this option allows to create the P2P Device interface correctly
when using P2P permanent groups, enabling wpa_supplicant to reuse the
same MAC address when re-invoking a P2P permanent group.

update_config=1 is required.
