Quite a lot of patches for rtlwifi and iwlwifi this time, but changes
also for other active wireless drivers.

Major changes:

ath9k

* add support for Dell Wireless 1601 PCI device

* add debugfs file to manually override noise floor

ath10k

* bump up FW API to 6 for a new QCA6174 firmware branch

wil6210

* support 8 kB RX buffers

iwlwifi

* work to support A000 devices continues

* add support for FW API 30

* add Geographical and Dynamic Specific Absorption Rate (SAR) support

* support a few new PCI device IDs

rtlwifi

* work on adding Bluetooth coexistance support, not finished yet

====================
My last pull request has been a while, we now have:
 * connection quality monitoring with multiple thresholds
 * support for FILS shared key authentication offload
 * pre-CAC regulatory compliance - only ETSI allows this
 * sanity check for some rate confusion that hit ChromeOS
   (but nobody else uses it, evidently)
 * some documentation updates
 * lots of cleanups

767c13e610 Annotate hardware config module parameters in drivers/net/wireless/ 
When the kernel is running in secure boot mode, we lock down the kernel to
prevent userspace from modifying the running kernel image.  Whilst this
includes prohibiting access to things like /dev/mem, it must also prevent
access by means of configuring driver modules in such a way as to cause a
device to access or modify the kernel image.

To this end, annotate module_param* statements that refer to hardware
configuration and indicate for future reference what type of parameter they
specify.  The parameter parser in the core sees this information and can
skip such parameters with an error message if the kernel is locked down.
The module initialisation then runs as normal, but just sees whatever the
default values for those parameters is.

Note that we do still need to do the module initialisation because some
drivers have viable defaults set in case parameters aren't specified and
some drivers support automatic configuration (e.g. PNP or PCI) in addition
to manually coded parameters.

This patch annotates drivers in drivers/net/wireless/.

d9158ea1d1 rtlwifi: btcoex: 21a 2ant: check power save state before pstdma 
The power_save_state function checks the state of power saving.
For tdma settings, the wifi sends nullfunc to pretend enter power saving
and then bt can transmit. Hence the coex needs to check the power status
before set the pstdma function.

patch makes us be able to modify bt power for multiple power gaps and we
can precisely adjust the bt power.
