It was possible to create/delete/start/stop
monitor vdev from a few places that were not
exclusively protected against each other. This
resulted in monitor vdev being stopped/removed by
one call origin while another one was expecting it
to continue running.

For example if CAC was started and interface's
promiscuous mode was toggled monitor vdev was
removed from the driver meaning no radar would be
detected. In additional a warning would be printed
upon CAC completion complaining it tried to stop
non-running monitor vdev.

The patch simplifies monitor code by removing
IEEE80211_HW_WANT_MONITOR_VIF (which wasn't really
ever needed) and improves state tracking. It also
unifies prints.

Since copy engine allocation has been revised the
ath10k_pci_ce_deinit() now simply zeroes copy
engine registers. It's probably a good idea to do
that before reseting for a more graceful device
reset.

Before ath10k_pci_ce_deinit() freed copy engine
ringbuffer memory so it was required to call it
after resetting. Otherwise it was possible for
device to access unmapped/freed copy engine
ringbuffer memory.

Definitions by which copy engine structure are
allocated do not change so it doesn't make much
sense to re-create those structures each time
device is booted (e.g. due to firmware recovery).

This should decrease chance of memory allocation
failures.

While at it remove per_transfer_context pointer
indirection. The array has been trailing the copy
engine ringbuffer structure anyway. This also
saves pointer size worth of bytes for each copy
engine ringbuffer.

RSSI and RATES fields are valid only when START_VALID
bit is set. So, in current implementation we have to
remember/caclulate them when START_VALID and report the same
when only END_VALID is set.
Currently during heavy traffic we could have:
- 10 packets with START_VALID - correct RSSI and RATES
- 10 packets with END_VALID
- 10 packets with START_VALID - correct RSSI and RATES
- 10 packets with END_VALID
...
Next using monitor interface we will see:
- 10 packets with correct rssi/rates
- 10 packets with rssi=-95/rate=6Mbps

Command WMI_FORCE_FW_HANG_CMDID is not supported in firmware 10.1.
In order to have firmware crash simulation functionality also
in firmware 10.1 driver can force firmware crash by performing not allowed
operation. Driver can deliberately crash firmware when setting vdev param for
vdev id out of range.  This patch introduces two keywords to simulate_fw_crash:

'soft' which will cause firmware crash that is recoverable
       by warm firmware reset but supported only in main firmware.
'hard' which will cause firmware crash recoverable by cold
       firmware reset, this option works for both firmwares.

Commands to trigger firmware soft/hard crash:

echo 'soft' > /sys/kernel/debug/ieee80211/phyX/ath10k/simulate_fw_crash
echo 'hard' > /sys/kernel/debug/ieee80211/phyX/ath10k/simulate_fw_crash
