When printing VRING on debugfs (file "vrings"),
software head & tail indexes were printed in decimal format
while hardware tail in hexadecimal only.

It is not comfortable to compare indexes in different formats;
on the other hand, hexadecimal output useful to see hardware
glitches.

To serve all purposes, print hardware tail in both decimal and

Introduce module parameter (int) agg_wsize. It can be changed on run time,
will be taken into account on the next connect. Interpretation:

- 0 - use automatically calculated window size
- >0 - use this for window size. Clipped by maximum supported by the hardware

Upon Tx vring creation, initiate BACK establishment
with maximum possible window size.

When establishing secure connection, there is EAPOL data exchange
between connection itself and "data port open", where security
is done and non-EAPOL data may be transferred. It is better to
send EAPOL frames using normal ACK because of firmware considerations.

- data port open for the corresponded STA
- vring created

Introduce BACK establishment procedures; decision logic is not implemented
yet; debugfs entry 'addba' used to manually trigger addba/delba for ringid 0.

debugfs usage:
to establish BACK with agg_wsize 16:
  echo 16 > /sys/kernel/debug/ieee80211/phy0/wil6210/addba
to delete BACK:
  echo 0 > /sys/kernel/debug/ieee80211/phy0/wil6210/addba
to change agg_wsize, one need to delete BACK and establish it anew

ADDBA flow for:

- originator

Tx side (initiator) sends WMI_VRING_BA_EN_CMDID providing
agg_wsize and timeout parameters.
Eventually, it gets event confirming BACK agreement - WMI_BA_STATUS_EVENTID
with negotiated parameters. On this event, update Tx vring data
(struct vring_tx_data) and display BACK parameters on debugfs

- recipient

Rx side (recipient) firmware informs driver about ADDBA with
WMI_RCP_ADDBA_REQ_EVENTID, driver process it in service work
queue wq_service. It adjusts parameters and sends response
with WMI_RCP_ADDBA_RESP_CMDID, and final confirmation provided
by firmware with WMI_ADDBA_RESP_SENT_EVENTID. In case of success,
driver updates Rx BACK reorder buffer.

policy for BACK parameters:
- aggregation size (agg_wsize * MPDUsize)) to not exceed 64Kbytes

DELBA flow for:

- originator

driver decides to terminate BACK, it sends WMI_VRING_BA_DIS_CMDID
and updates struct vring_tx_data associated with vring; ignore
WMI_DELBA_EVENTID.

- recipient

firmware informs driver with WMI_DELBA_EVENTID,
driver deletes correspondent reorder buffer

ADDBA request processing requires sending WMI command, therefore
it is processed in work queue context. Same work queue used as for
connect, it get renamed to wq_service

* Device tree support

* Major restructuring how to handle different WMI interface versions

* Add WMI TLV interface in preparation for new firmware interface support

* Support new firmware branch 10.2.4

* Add thermal cooling interface

* Add hwmon interface to read temparture from the device

And of course lots of small fixes and cleanups.
