Group keys in IBSS or AP mode are not programmed
into the device since we give the key to it with
every TX packet. However, we do need mac80211 to
create the MMIC & PN in all cases. Move the code
around to set the key flags all the time. We set
them even when the key is removed again but that
is obviously harmless.

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

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,

Johannes' patch for "cfg80211: fix regulatory NULL dereference"
broke user regulaotry hints and it did not address the fact that
last_request was left populated even if the previous regulatory
hint was stale due to the wiphy disappearing.
Fix user reguluatory hints by only bailing out if for those
regulatory hints where a request_wiphy is expected. The stale last_request
considerations are addressed through the previous fixes on last_request
where we reset the last_request to a static world regdom request upon
reset_regdomains(). In this case though we further enhance the effect
by simply restoring reguluatory settings completely.

There is a theoretical race that if hit will trigger
a crash. The race is between when we issue the first
regulatory hint, regulatory_hint_core(), gets processed
by the workqueue and between when the first device
gets registered to the wireless core. This is not easy
to reproduce but it was easy to do so through the
regulatory simulator I have been working on. This
is a port of the fix I implemented there [1].

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.
