mac80211: backport brcmfmac fixes & debugging helpers from 4.18
The most important is probably regression fix in handling platform
NVRAM. That bug stopped hardware from being properly calibrated breaking
e.g. 5 GHz for Netgear R8000.
Other than that it triggers memory dumps when experiencing firmware
problems which is important for debugging purposes.
