From: Sean Wang <sean.wang@xxxxxxxxxxxx>
When .sta_state is implemented, mac80211 assumes that the station entry is
usable after the NOTEXIST->NONE transition.
So we should create the sta entry as early as possible in order that
mac80211 pass assoc/auth frames to mt76 with the newly created sta entry,
and add .sta_assoc to mt76 core to refresh the sta entry again when sta is
being associated.
Fixes: 8aa5a9b7361c ("mt76: mt7921: enable deep sleep at runtime")
Signed-off-by: Sean Wang <sean.wang@xxxxxxxxxxxx>

v1->v2: Put back the careless change not belonged to the patch to keep
mt7921_mcu_sta_add for BC entry and mt76_connac_mcu_uni_add_bss
on the association.
v2->v3: 1. rebase the latest mt76
2. squashing 2/3 to the one
3. add the proper lock in mt7921_mac_sta_assoc
v3->v4: 1. drop mt76_connac_mcu_add_sta_cmd, call mt76_connac_mcu_sta_cmd
instead
2. drop mt76_connac_mcu_update_sta_cmd, call
mt76_connac_mcu_sta_cmd instead
3. squash the patch 1/2
4. drop mt7921_mcu_sta_add, call mt7921_mcu_sta_update instead
5. rebase onto the top of the latest mt76 plus
“mt76: connac: fix UC entry is being overwritten”
6. move .newly to be one of parameters in struct mt76_sta_cmd_info
v4->v5: include back the changelog
