wireless-drivers-next patches for 4.17

Smaller new features to various drivers but nothing really out of
 ordinary.
 
 Major changes:
 
 ath10k
 
 * enable chip temperature measurement for QCA6174/QCA9377
 
 * add firmware memory dump for QCA9984
 
 * enable buffer STA on TDLS link for QCA6174
 
 * support different beacon internals in multiple interface scenario
   for QCA988X/QCA99X0/QCA9984/QCA4019
 
 iwlwifi
 
 * support for new PCI IDs for the 9000 family
 
 * support for a new firmware API version
 
 * support for advanced dwell and Optimized Connectivity Experience
   (OCE) in scanning
 
 btrsi
 
 * fix kconfig dependencies
 
 wil6210
 
 * support multiple virtual interfaces
