a4aab099cc ath10k: fix spectral scan for QCA99X0 family of chipsets 
spectral_bin length (number of bins per fft sample) is usually
a value where (2^n = value), n is an integer.  All of the QCA99X0
family of chipsets seems to report a spectral_bin length of
2^n + 'm' bytes, where m = 4, 12 based on the chipset. This 'm'
bytes seems to carry some radar related info which is currently
discarded only for 'bin_len = 68' bytes. Extend this discarding of
irrelevant 'bin_len' for QCA9984, QCA9888, IPQ4019 as well by
introducing a hardware parameter 'spectral_bin_discard'. Also
for QCA988X based family of chipsets which doesn't seem to have this
issue and also for some of the hardware which I have not tested
like QCA6174/QCA9377 the existing behaviour is retained as it is.

1f242a3de7 rt2x00: reverse external PA capability flag logic 
Consequently refer to external PA instead of inverting the logic and
use an internal PA capability flag which is a bit confusing.
Currently this is used for Rt3352 only, but MT7620A also allows for an
external PA which will be supported by a follow up patch.

4da5e7ea13 rtlwifi: btcoex: 21a 1ant: avoid LPS/IPS mismatch for pnp notify 
When driver is going to sleep, it does not leave LPS/IPS, thus the
BTCoex may have mismatch when driver wakes up. To avoid that, BTCoex
needs to clear the IPS/LPS state when it receives a pnp notify, then
it can properly set up the hw when driver wakes up.

During hw initialisation, wifi may be ready after bt has already been
ready, which causes bt to act abnormally. To avoid this, set GNT_BT to
high during hw init.

If bt is queing, we need to set the packet priority properly.
Originally we only consider if wifi was connected or not, but now we
also consider if bt is under abnormal scan or wifi is scanning, roaming
or linking, and set the coex table.

609d59acb6 rtlwifi: btcoex: 23b 2ant: add pnp notidy to avoid LPS/IPS mismatch 
When driver is going to sleep, it does not leave LPS/IPS, thus the
BTCoex may have mismatch when driver wakes up. To avoid that, BTCoex
needs to clear the IPS/LPS state when it receives a pnp notify, then
it can properly set up the hw when driver wakes up.

b01127b268 rtlwifi: btcoex: 23b 2ant: check PS state before setting tdma duration 
For time division multiple access, the wifi and bt take turns to
transmit, but we need to let AP know that wifi is under standby mode by
sending null data to "pretend" entering power saving state using lps
rpwm.

But, the fw does not know if it is the actual power saving mode or just a
fake one to cheat to the AP. Hence, before fw setting the tdma duration,
the fw needs the driver to check the power saving state first.
