wireless-drivers fixes for 4.15

Browse Source 
Second set of fixes for 4.15. This time a lot of iwlwifi patches and
 two brcmfmac patches. Most important here are the MIC and IVC fixes
 for iwlwifi to unbreak 9000 series.
 
 iwlwifi
 
 * fix rate-scaling to not start lowest possible rate
 
 * fix the TX queue hang detection for AP/GO modes
 
 * fix the TX queue hang timeout in monitor interfaces
 
 * fix packet injection
 
 * remove a wrong error message when dumping PCI registers
 
 * fix race condition with RF-kill
 
 * tell mac80211 when the MIC has been stripped (9000 series)
 
 * tell mac80211 when the IVC has been stripped (9000 series)
 
 * add 2 new PCI IDs, one for 9000 and one for 22000
 
 * fix a queue hang due during a P2P Remain-on-Channel operation
 
 brcmfmac
 
 * fix a race which sometimes caused a crash during sdio unbind
 
 * fix a kernel-doc related build error
