wil6210:
* support Wi-Fi Simple Configuration in STA mode
iwlwifi:
* a few fixes (re-enablement of interrupts for certain new
platforms that have special power states)
* Rework completely the RBD allocation model towards new
multi RX hardware.
* cleanups
* scan reworks continuation (Luca)
mwifiex:
* improve firmware debug functionality
rtlwifi:
* update regulatory database
brcmfmac:

Conflicts:
drivers/net/wireless/iwlwifi/Kconfig
Trivial conflict in iwlwifi Kconfig, two commits adding
the same two chip numbers to the help text, but order
transposed.
