Merge tag 'iwlwifi-next-for-kalle-2020-04-24-2' of git://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/iwlwifi-next

First set of iwlwifi patches intended for v5.8

* TX queue debugfs improvements;
* Support for a few new FW API versions;
* Remove deprecated scan FW API version;
* New hw configs and other related changes;
* Support for NPK buffers in debugging;
* More debugging fetures;
* Some other small fixes and clean-ups;
