Emmanuel Grumbach aee8bf5d26 iwlwifi: mvm: BT Coex - update the new API
The firmware was not using the new API, so we don't need to
differentiate between the different stages of this new API.
The main difference here is that most of the hard coded
values are not sent through the command anymore.

Emmanuel Grumbach 123f515635 iwlwifi: mvm: BT Coex - add support for TTC / RRC
The TTC and RRC features are supported by the newer
firmwares. It allows to reach better overall WiFi and BT
performance. When the RRC is enabled, we don't need to force
the AP to send SISO frames, but it can keeps sending MIMO
frames.

Johannes Berg 8b4139dc9f iwlwifi: add Intel Mobile Communications copyright
Our legal structure changed at some point (see wikipedia), but
we forgot to immediately switch over to the new copyright
notice.

For files that we have modified in the time since the change,
add the proper copyright notice now.

Emmanuel Grumbach 1459f269e8 iwlwifi: mvm: BT Coex - fix the ACK / CTS kill mask
According to new requirements, the ACK / CTS kill mask is
not related to reduced TX power anymore. This allows to
remove the code that tracked reduced TX power enablement
across different interfaces.
The ACK / CTS kill mask is now fetch from a table. It
depends on the Activity grading (activity from BT) and on
the Look Up Table (LUT) type.

Emmanuel Grumbach 4c86f938d3 iwlwifi: mvm: BT Coex - relax constraints when TTC / RRC is active
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.

Emmanuel Grumbach 430a3bbafd iwlwifi: mvm: BT Coex - new API
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.

Emmanuel Grumbach 0ea8d0432c iwlwifi: mvm: BT Coex - prepare towards new API
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.

When the firmware enables TxTxCorunning, we can lift the
constaints on the rate control.

Emmanuel Grumbach e78973efe7 iwlwifi: mvm: BT Coex - minor API change
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.

Emmanuel Grumbach cdb00563fe iwlwifi: mvm: BT Coex - add debugfs hook to set BT Tx priority
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.
