mac80211: add IEEE80211_KEY_FLAG_GENERATE_MMIE to ieee80211_key_flags
Add IEEE80211_KEY_FLAG_GENERATE_MMIE flag to ieee80211_key_flags in order
to allow the driver to notify mac80211 to generate MMIE and that it
requires sequence number generation only.
This is a preliminary patch to add BIP_CMAC_128 hw support to mt7615
driver
