Move mac_work delayed work in mt76_dev data structure since
it is used by all drivers and it will be reused adding mac work to
mt7615

All mt76 drivers (now also USB drivers) require empty .set_tim
callback. Add it to common mt76 module and use on all drivers.

If the MT_TXD3_SN_VALID flag is not set in the tx descriptor, the hardware
assigns the sequence number. However, the rest of the code assumes that the
sequence number specified in the 802.11 header gets transmitted.
This was causing issues with the aggregation setup, which worked for the
initial one (where the sequence numbers were still close), but not for
further teardown/re-establishing of sessions.
Additionally, the overwrite of the TID sequence number in WTBL2 was resetting
the hardware assigned sequence numbers, causing them to drift further apart.
Fix this by using the software assigned sequence numbers

Introduce mt76_sw_queue data structure in order to support new
chipsets (e.g. mt7615) that have a shared hardware queue for all traffic
identifiers. mt76_sw_queue will be used to track outstanding packets

These packets have no txwi entry in the ring, so tracking via tx status does
not work. To prevent PS poll requests from being unanswered, end the service
period right away

energy detect values are above the threshold.

Use PSE registers to loop back any pending tx packets for a client that
just went to sleep back into the MCU rx queue.
Re-queue those packets to the tx queue immediately after a client wakes up.

There is some code in the mac80211 tx status processing code that could
potentially call back into the tx codepath.
To avoid deadlocks, make sure that no tx related spinlocks are taken
during the ieee80211_tx_status call.
