When adding new radio via HWSIM_CMD_NEW_RADIO then listeners on the
multicast group "config" are informed.
While at it, refactor the configuration parameters to be able to
pass them directly and have fewer function arguments.

In some cases hw recovery was taking an absurdly
long time due to ath10k waiting for things that
would never really complete.
Instead of waiting for inevitable timeouts poke
all completions and wakequeues and check if it's
still worth waiting.
Reading/writing ar->state requires conf_mutex.
Since waiters might be holding it introduce a new
flag CRASH_FLUSH so it's possible to tell waiters
to abort whatever they were waiting for.

Until now it was possible to simulate soft and
hard fw crashes but it wasn't possible to trigger
an immediately hw restart itself (without the fw
crash).
This can be useful when stress testing hw
restarting stability, e.g. during heavy tx/rx
traffic.

While testing other things I've found that CE
items aren't cleared properly. This could lead to
null dereferences in BMI.
To prevent that make sure CE revoking clears the
nbytes value (which is used as a buffer completion
indication) and memset the entire CE ring data
shared between host and target when
(re)initializing.
Also make sure to check BMI xfer pointer and print
a splat instead of crashing the kernel.

One of the problems with warm reset I've found is
that it must be guaranteed that copy engine
registers are not being accessed while being
reset. Otherwise in worst case scenario the host
may lock up.
Instead of using sleeps and hoping the device is
operational in some arbitrary timeframes use
firmware indication register.
As a side effect this makes driver
boot/stop/recovery faster.

Disconnect flow may be invoked either from upper layer request,
or from event reported by the firmware.
In case of firmware event, driver need to release resources for the station but
not send another disconnect WMI command.
In case of upper layer request, WMI_DISCONNECT_STA_CMDID command need to
be issued for the firmware to perform disconnect on the MAC layer. Eventually,
event is expected to confirm MAC disconnect, but it is better to not wait for
firmware event and release station resources immediately. FW may fail to
report disconnect for various reasons, so one could not rely on event always reported.
Introduce parameter to distinguish 2 cases above to prevent double WMI command
issuing.
