[PATCH v2 2/4] wifi: mt7601u: enable AP and Wi-Fi Direct interface modes

[John Robin <johnrobin044@gmail.com>]

Register the AP, P2P_GO, P2P_CLIENT, and ADHOC interface modes in
mac80211 to allow for concurrent Station and AP operation. This
defines an interface combination supporting up to 2 concurrent modes
and sets NEEDS_UNIQUE_STA_ADDR so mac80211 can automatically generate
MAC addresses for the virtual interfaces.
