The firmware decided to not implement this API in this way,
so for now remove setting the field completely. This will
allow the firmware to change how to use this field later.

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.

7265 features a new calibration which is called antenna
coupling. The purpose of this calibration (which isn't
really a calibration), is to measure the isolation between
the antennas and that can give us useful information for
the Coex modules.
With this information, we can tune the LookUpTables (LUTs)
that define the BT / WiFi contention policy.
The LUTs currently contain dummy values - but they will be
updated soon.
While at it, change the current code to stop duplicate the
host command while sending. This was needed back then, when
the command was short enough to be allocated on the stack.
Since then, the command grew a lot and is now allocated on
the heap - hence we can use the NOCOPY option instead.

The Sync to SCO is a feature that allows to synchronize
between the WiFi traffic and the expectable BT traffic
when SCO profile is active.
We need to set the validity bit in the command in the init
flow, and set / clear the enablement bit if we want to
enabled / disable the feature.
While at it, clean up the flags that are not used in the
API.
This feature needs to be enabled / disabled easily, so
export its enablement to constants.h.

Limit the scheduling duration of bindings without a low-latency
interface in the firmware, this prevents those bindings from
occupying the medium for a period of time longer than what we
want for the other interfaces in low-latency mode.
As older firmware doesn't do anything with the max_duration field
and ignores it completely, there's no need for a firmware flag.

If there is/are interface(s) in low-latency mode, reserve a
percentage (currently 64%) of the quota for that binding to
improve the quality of service for those interfaces. However,
if there's more than one binding that has low-latency, then
give up and don't reserve, we can't allocate more than 100%.

Adjust the following:
- RX/TX AP-to-PSM timeout in case of uAPSD and PBW snoozing
- PSM-to-AM TX/RX heavy traffic thresholds
- Beacon abort escape timer for D3/D0i3

The Performance Based Window snooze mechanism is based on uAPSD and is
used in low-medium traffic scenarios, in order to provide better power
performance while insuring low latency and jitter for the incoming traffic.
This patch enables PBW snoozing in case uAPSD is enabled and all ACs are
uAPSD trigger and delivery enabled.

Implement basic uAPSD client support adding the following:
- Advertise uAPSD support in HW capabilities
- Set all ACs trigger- and delivery-enabled
- Set max SP length to 2 buffered frames
- Assign QNDP with the highest TID with no mandatory admission
control required
- Set uAPSD related parameters in Power Table command

To make maintaining some constant default values in the
driver easier, declare them in a separate file.
