wireless-drivers fixes for 4.12

Browse Source 
It has been a slow start of cycle and this the first set of fixes for
 4.12. Nothing really major here.
 
 wcn36xx
 
 * fix an issue with module reload
 
 brcmfmac
 
 * fix aligment regression on 64 bit systems
 
 iwlwifi
 
 * fixes for memory leaks, runtime PM, memory initialisation and other
   smaller problems
 
 * fix IBSS on devices using DQA mode (7260 and up)
 
 * fix the minimum firmware API requirement for 7265D, 3168, 8000 and
   8265
