When we load the firmware for the 8000 B step device, it'll
verify its signature. In the current version of the
hardware, there can be a race between the WiFi firmware
being loaded and the Bluetooth firmware being loaded.

Check that WiFi is authenticated, if not, take ownership
on the authentication machine to make sure that the WiFi
firmware will be authenticated.

When entering D0i3, the MVM mutex cannot be grabbed. This interferes
with the calculation of the number of connected TDLS stations during
the setup of the power cmd.
The goal is to disable power saving for all vifs while any TDLS station
is connected. For this purpose it is enough to keep the pm_enabled
member of all mvmvifs as false. An update of the power state already
occurs when a TDLS station is added/removed, so the values are correctly
updated.

We don't need to acquire MAC access for each access, it
makes much more sense to keep the MAC access. This speeds
up the Tx DMA stop flow significantly.
Moreover, if one channel can't be stopped, stop the others
but don't poll for them to avoid being stuck there for a
long time.

This solves a situation in which we were stuck in that flow
for way too long with a spinlock held which led to a kernel
panic.

Sometimes the firmware will have a hard coded configuration.
In this case, the driver won't find any configuration
in the firmware file, and it will have to re-start
recording in case it has been stopped. This can't be done
by the configuration host command since there is no such
host command configured. Do that with the registers instead.
