Implement connection quality monitoring similar to the wl1271 driver.
It triggers ieee80211_cqm_rssi_notify with the corresponding event when
RSSI drops blow RSSI threshold or rises again above the RSSI threshold.
It should be noted that wl1251 doesn't support RSSI hysteresis, instead it
uses RSSI averageing and delays events until a certain count of frames
proved RSSI change.

The queue stopping/waking functionality was broken in a way that could
cause the TX to stall if the right circumstances are met.

The problem was caused by tx_work, which is scheduled on each TX operation.
If the firmware buffer is full, tx_work does nothing. In combinition with
stopped queues or non-continues transfers, tx_work is never scheduled again.
Moreover the low watermark introduced by
9df86e2e never takes effect because of some
old code.

Solve this by scheduling tx_work every time tx_queue is non-empty and
firmware buffer is freed on tx_complete.

This also solves a possible but unlikely case: If less frames than the high
watermark are queued, but more than firmware buffer can hold. This results
in queues staying awake but the only scheduled tx_work doesn't transfer all
frames, so the remaining frames are stuck in the queue until more frames
get queued and tx_work is scheduled again.

The I/Q swapping is extremely important and should be dealt with extra care.
It will affects OFDM and CCK differently.

devices, it is in non-swapped status (but its swapped with respected to 6000/6005/6030).

The TX/RX work structures must be able to run independently
of other workqueues. This is because mac80211 might use
the flush() callback function from various context, which depends
on the TX/RX work to complete while the main thread is blocked
(until the the TX queues are empty).

This should reduce the number of  'Queue %d failed to flush' warnings.
