here we check for BT state and if BT calibration has started,
give 25ms for BT Calibration to finish. we also take care of 2G/5G
switch and LNA transfer incase WLAN is operating in 5G. in case the BT
state is awake when we do WLAN calibration re-calibrate and we reset
the message exchange between WLAN and BT. BT is given preference when
simultaneous CAL request happens. calibration for WLAN/BT is done
assuming that the other co-existing module is in awake state, if not
we continue to do calibration while if the other module's state changes
we need to do restart the calibration handshake

WLAN communicates with BT for its calibration by sending WLAN_CAL_REQ,
waits for BT_CAL_GRANT. This is done with the help of GPM messages.
also WLAN_CAL_DONE messages is sent once WLAN calibration is done.

The on-channel work optimisations have caused a
number of issues, and the code is unfortunately
very complex and almost impossible to follow.
Instead of attempting to put in more workarounds
let's just remove those optimisations, we can
work on them again later, after we change the
whole auth/assoc design.

This should fix rate_control_send_low() warnings,

This makes handling the calibration data more generic
and no longer requires updating IWL_CALIB_MAX when a
new uCode comes with more calibration packets. Since
we just copy the data back, there's also no need for
understanding which calibration we received -- we can
just reflect it back to the runtime uCode.

The init microcode knows very well which calibrations
are required and sends us results for those that are.
Consequently, we can just send all of those to the RT
uCode again.

The problem with having the driver know about this is
that it is a uCode feature, not a hardware feature so
the config is completely unsuitable.

The only thing we need to check is whether the device
needs crystal calibration or not, add a new parameter
to the configuration for that.

This makes new uCode work on 6000 series devices.

According to documentation higher DCUs have higher priority and should
be used for beacons and CAB traffic. More specifically DCU 9 should be
used for beacons and DCU 8 for CAB traffic, I assumed DCU 7 should be
OK for UAPSD traffic.

Note that DCU 8 and 9 are special because they can only be mapped to a single
QCU each but since we use a 1:1 mapping between QCUs and DCUs anyway we don't
have to change much.

P.S. I also did a few related cleanups on qcu.c and ath5k.h
