When TxTxCo-Running is active, we can relax the constraints
on the rate control.
When RxRxCo-Running is active, we can relax the constrains
on SMPS.

No need to send the big BT_COEX_CMD command, we have now
a much thiner command that updates only what is needed.
Adapt the code to that.

Start the new BT Coex implementation.
Don't react to notifications for now - only the initial
configuration is implemented. The rest will happen in next
patches.
Since coex.c now uses the new the new structures in all
functions, we need to adapt the code to compile, even if it
doesn't run yet.

A new API is coming. This new API is not backward
compatible. So we need to keep the old commands to be able
to work with the former API.
Move all the current code into a new file: coex_legacy.
If a firmware with the new API is detected, we currently
just bail out since the implementation of the new API will
come in future patches.

If BT is active, we need to refrain from using the shared
antenna. This logic is done in the firmware when we use the
link quality tables. But for management frames, the rate is
written in the Tx command by the driver.
Hence the driver needs to make sure not use the shared
antenna when BT is active for any frames that don't use
the rate scale table such as management frames or multicast.

We can Tx in MIMO rates when we are in TxTx Disallow mode
just like we can when we are in Tight mode.
Same if we are in 5Ghz regardless of the mode we are.
Change the code to allow MIMO in these cases.

Fix this by simply removing its definition.

The commit below introduced a bug in the validity bits in
init. Due to that, all the Coex mechanism stopped sending
kills to the BT side. Fix that.

Calling iwl_send_bt_init_conf for INIT firmware is not a
problem, and calling iwl_send_bt_prio_tbl from
iwl_send_bt_init_conf allows us to prepare for new API.

The BT Coex API underwent a minor backward compatible API
change.
We now need to set an invalid value in the override fields.
While at it, add kerneldoc comments on the fields in the
command.

In order to debug the firmware, we need to be able to set
the BT priority of WiFi packets. This priority is set based
on the type of the packet (control frames, EAPOL etc...).
For debugging purposes, allow to override this priority by
a debugfs controlled value.
Enable this feature that needs this priority to be able to
test it.

We can now define the priority against BT per AC. This is
possible with a newer firmware that allows to define the
priority with 2 bits.
Note that this change is compatible with older firmware
since older firmware will simply ignore the new bit (11),
and we still set the old bit (12) in the same cases as
before.

This code is really related to BT Coex - move it to the coex
file.
Also - prepare for a FW API change that will happen soon:
Bits 11 and 12 will be allocated for BT priority. Today, we
only have bit 12.
