This pick most of brcmfmac changes backported into the master in commits
5932eb690f ("mac80211: brcmfmac: backport firmware loading cleanup")
3eab6b8275 ("mac80211: brcmfmac: backport NVRAM loading improvements")
529c95cc15 ("mac80211: brcmfmac: fix use-after-free & possible NULL pointer dereference")
It's more than would be normally backported into a stable branch but it
seems required. Firmware loading cleanups are needed to allow fix memory
bugs in a reliable way. Memory fixes are really important to avoid
corrupting memory and risking a NULL pointer dereference.
Hopefully this stuff has received enough testing in the master.

There was a bug in brcmfmac patch that could result in treating random
memory as source of country codes.

This allows some basic region switching on Netgear R8000. More devices &
codes may be added. Ideally it should be converted into DT info & patch.
