====================
wireless-drivers-next patches for 4.21

First set of patches for 4.21. Most notable here is support for
Quantenna's QSR1000/QSR2000 chipsets and more flexible ways to provide
nvram files for brcmfmac.

Major changes:

brcmfmac

* add support for first trying to get a board specific nvram file

* add support for getting nvram contents from EFI variables

qtnfmac

* use single PCIe driver for all platforms and rename
  Kconfig option CONFIG_QTNFMAC_PEARL_PCIE to CONFIG_QTNFMAC_PCIE

* add support for QSR1000/QSR2000 (Topaz) family of chipsets

ath10k

* add support for WCN3990 firmware crash recovery

* add firmware memory dump support for QCA4019

wil6210

* add firmware error recovery while in AP mode

ath9k

* remove experimental notice from dynack feature

iwlwifi

* PCI IDs for some new 9000-series cards

* improve antenna usage on connection problems

* new firmware debugging infrastructure

* some more work on 802.11ax

* improve support for multiple RF modules with 22000 devices

cordic

* move cordic macros and defines to a public header file

* convert brcmsmac and b43 to fully use cordic library
