For a000 FW moved to 15 as management TID.
The change for us is fairly local - translate old TID to 15
when enabling and disabling a queue, and make sure to cover
it also on TX responses.

a000 devices queue management is going to change significantly.
We will have 512 queues. Those queues will be assigned number
by the firmware and not by the driver.
In addition, due to SN offload having TX queue shared between TIDs
is impossible
Also, the ADD_STA command no longer updates queues status.
The only point of changing queue in the SCD queue config API.
From driver perspective we have here a new design:
Queue sharing and inactivity checks are disabled.
Once this is done, the only paths that call scd_queue_cfg command
are paths that alloc and release TX queues - which will make future
accommodation to queue number assignment by FW easier.
Since allocating 512 queues statically is not advisable, transport
will allocate the queue on demand, fill the command with DRAM data
and send it. This is reflected in the new transport API.

In a000 devices the TX handling is different in a few ways:
* Queues are allocated dynamically
* DQA is enabled by default
* Driver shouldn't access TFH registers - ucode configures it
all in SCD_QUEUE_CFG command
Support all this in a new API with op mode, where op mode sends
the command, transport will allocate the queue dynamically, fill
in DMA properties, send the command to FW and get the ID back.
Current implementation only sets the new transport API and fills
the DMA properties.
Future patches will complete the other parts.

Dynamic SAR allows changing TX power limits at runtime to comply with
SAR regulations on multiple form factors (e.g. tablet vs. clamshell
mode). To support this, a new table was added to ACPI, which is
called Extended Wireless Regulatory Descriptor (EWRD). This table
allows OEMs to define different TX power profiles for each form-factor
or usage mode.
Read this new table and store it in our SAR profiles table, in
preparation for Dynamic SAR support.

We are adding support for dynamic TX power tables for SAR (specific
absorption rate) compliance. Currently, we only support a single
(static) TX power table, which is read from ACPI, and use it
statically.
To prepare for more tables that can be switched dynamically, refactor
the SAR init flow to allow reusage and add the current static table as
a single entry in an array of tables.

In a000 devices we will support up to 32 stations.
The max station define is used also for invalid station marking
which makes finding usages of actual maximum station pretty hard
to sort through - change it to be a different define in order
to make future changes easier.
Use also ARRAY_SIZE intead of define when possible.
Do not move yet to 32 stations until firmware do it though.

Currently aux & broadcast queues are added before calling add
station, which results with a SCD_QUEUE_CFG command sent with
a station id unknown yet to fw.
While this works for pre-a000 firmware, the a000 fw requires
the order to be reversed.
The reason the change is only for a000 devices and not for
previous devices is that we cannot reverse the order since
the tfd_queue_mask containing the aux queue will cause FW to
assert on adding a queue mask with a queue that is not enabled.
This is not a problem in a000 fw since the tfd_queue_mask was
removed from the add sta API.

As per latest regulatory update for India, channel 52, 56, 60, 64
is no longer restricted to DFS. Enabling DFS/no infra flags in driver
results in applying all DFS related restrictions (like doing CAC etc
before this channel moves to 'available state') for these channels
even though the country code is programmed as 'India' in he hardware,
fix this by relaxing the frequency range while applying RADAR flags
only if the country code is programmed to India. If the frequency range
needs to modified based on different country code, ath_is_radar_freq
can be extended/modified dynamically.

Introduce a debugfs option to manually override the noise floor,
ignoring the automatically tuned noise floor of the driver/hw.
In my tests with a AR9580 based module and a tx99 5 MHz interferer,
I could tune the noisefloor to -95 dBm or above to allow communication
again. The automatic noise floor calibration sometimes could adapt to
the situation as well, but not reliably and permanently.
I would consider this "feature" experimental and interesting for people
debugging the noise floor calibration or other effects of the hardware.

spectral_bin length (number of bins per fft sample) is usually
a value where (2^n = value), n is an integer. All of the QCA99X0
family of chipsets seems to report a spectral_bin length of
2^n + 'm' bytes, where m = 4, 12 based on the chipset. This 'm'
bytes seems to carry some radar related info which is currently
discarded only for 'bin_len = 68' bytes. Extend this discarding of
irrelevant 'bin_len' for QCA9984, QCA9888, IPQ4019 as well by
introducing a hardware parameter 'spectral_bin_discard'. Also
for QCA988X based family of chipsets which doesn't seem to have this
issue and also for some of the hardware which I have not tested
like QCA6174/QCA9377 the existing behaviour is retained as it is.
