This patch introduce new RF code for rtl8225 zebra v4 radio
frontend.
This code contains a lot of black magic and it can work probably
only with the radio embdedded in the rtl8187se single-chip.

On currently supported HW there are four TX queues (three for normal
packets and one for beacons).
The driver uses just one TX queue, and declare to mac80211 to
support just one queue, but it allocates coherent memory for all
queues.
Furthermore the TX is code is written assumimg four queues exists,
and even if we decide to enable more queues in future, its mapping
rule to mac80211 is fixed.
This means we have memory waste on rtl8180/rtl8185, and we have also
not enough flexibility to add support for boards (rtl8187se) that
will use more queues.
This patch changes things in order to allocate coherent memory only
for the queues effectively used and it make it possible to specify
how to map hardware queues on mac80211 queues, that will be used
by rtl8187se code as soon it will be merged.
Note: even if the beacon queue is currently unused, this should
change, so I kept it.

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

The watchdog thread waits on completion that is set from a timer. As
the completion is count based this could mean that on a busy system
the watchdog is handled multiple times with a very short interval.
This is not the intended behaviour. After handling the watchdog it
should wait for the next timer expiry. This is accomplished by
reinitializing the completion.
