mac80211: brcmfmac: backport 4.19 patches preparing monitor mode support

Monitor mode isn't supported yet with brcmfmac, it's just an early work.
This also prepares brcmfmac to work stable with new firmwares which use
updated struct for passing STA info.

+Subject: [PATCH] brcmfmac: detect firmware support for radiotap monitor frames
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Depending on used build-time options some firmwares may already include
+radiotap header in passed monitor frames. Add a new feature flag to
+store info about it. It's needed for proper handling of received frames
+before passing them up.
