mac80211: add pending brcmfmac patches fixing multiple interfaces

So far support for multiple interface was somehow broken in brcmfmac.
Driver couldn't correctly match firmware and system interfaces resulting
in not working APs and WARNINGs. This pending patches fixes that :)

+Subject: [PATCH] brcmfmac: use brcmf_get_ifp() to map ifidx to struct
+ brcmf_if instance
+
+The knowledge on how to map the interface index to a struct brcmf_if
+instance is in brcmf_get_ifp() so use that function when only the
+interface index is known instead of accessing brcmf_pub::iflist
+directly.
