The scheduler is a HW sub-block that directs the work of the Flow
Handler by issuing requests for frame transfers, specifying source
and destination. Its primary function is to allocate flows into the
TX FIFOs based upon a pre-determined mapping.
The driver has some responsibilities to the scheduler, namely
initialising and maintaining the hardware registers. This is
currently done by directly accessing them, which can cause races
with the firmware also accessing the registers.
To address this problem, change the driver to no longer directly
access the registers but go through the firmware for this if the
firmware has support for DQA and thus the new command.

The NoA duration for a GO is half the beacon interval
and a concurrent context like a STA can be active only
for that duration, before switching back to the GO's
operating channel.
Currently, when multiple beacons are missed, the dwell
time for the STA context is extended to improve the
chances of receiving a beacon. But the NoA is not updated
and this will cause problems since the GO is offline
for a period that is longer than the advertised duration.
Fix this by ensuring that the NoA is updated first before
extending the time slot for the STA context. Also make
sure that non-periodic NoA is used for a one-time, longer
absence period.

Reason is the following: when removing Rx vring
(wil_netdev_ops.ndo_stop -> wil_stop -> wil_down -> __wil_down -> wil_rx_fini),
Rx interrupt occurs. It trigger Rx NAPI, calling wil_rx_handle() that reaps
(already cleaned) buffer, causing skb referring to garbage memory being set into reorder buffer.
Then, network stack trying to access this buffer and fails.
Prevent Rx NAPI from being scheduled if device going to stop. Bit wil_status_napi_en reflects
NAPI enablement state, check it when triggering Rx NAPI.
Testing shows that check for wil_status_napi_en sometimes gets negative, and new error message
get printed - in this case kernel oops would be observed. Original oops is no more reproducible.
This change requires also changes in the AP flows.
Properly enable/disable NAPI for the AP. Make sure Rx VRING is disabled
when resetting target.
For this, promote __wil_up() and __wil_down() to the module scope, and use it
in the relevant flows.
