Rafał Miłecki 29aab93ea2 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.

brcmfmac: do not use internal roaming engine by default
Some evidence of curing disconnects with this disabled, so make it a default.
Can be overridden with module parameter roamoff=0
