Merge tag 'iwlwifi-next-for-kalle-2017-06-06' of git://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/iwlwifi-next

First batch of iwlwifi driver patches 4.13

* Loads of FW API documentation improvements (for tools and htmldoc);
* Continued work for the new A000 family;
* Bumped the maximum supported FW API to 31;
* Improve the differentiation between 8000, 9000 and A000 families;
* A lot of fixes and cleanups here and there;

kvalo: There were conflicts iwl_mvm_stop_device() and
iwl_mvm_tcool_set_cur_state(). The former was easy but latter needed more
thought. Apparently the mutex was taken too late, so I fixed so that the mutex
is taken first and then check for iwl_mvm_firmware_running().
