mac80211: brcmfmac: backport BCDC layer changes from kernel 4.12

Those changes are needed for backporting more recent crash fixes. There
are quite many BCDC patches but it's hopefully a very well tested code
by now.

+Subject: [PATCH] brcmfmac: ignore interfaces when fwsignal is disabled
+
+When brcmf_fws_add_interface() is called the struct brcmf_if::fws_desc
+field is initialized regardless the state of the fwsignal functionality,
+ie. the fcmode. This is not needed when fcmode is NONE, which is the
+default mode.
