Merge tag 'iwlwifi-next-for-kalle-2017-11-29' of git://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/iwlwifi-next

First batch of iwlwifi updates for v4.16

* Rename the temporary name A000 to 22000;
* Change in the way we print the firmware version;
* Remove some unused code;
* Other small improvements;

kvalo:

There were conflicts, I fixed them with taking into account commit c2c48ddfc8b0
("iwlwifi: fix firmware names for 9000 and A000 series hw"):

CONFLICT (content): Merge conflict in drivers/net/wireless/intel/iwlwifi/iwl-config.h
CONFLICT (modify/delete): drivers/net/wireless/intel/iwlwifi/cfg/a000.c deleted in ca495785063c428641cc6df8888afd2587ca6677 and modified in HEAD. Version HEAD of drivers/net/wireless/intel/iwlwifi/cfg/a000.c left in tree.
