mac80211: brcmfmac: add 2 more recent changes

First one is a fix for reporting channels to the user space. Important
for users as they could try setting invalid channel and fail to start an
interface.

Later is a support for newer FullMAC chipset firmwares.

+Subject: [PATCH] brcmfmac: support STA info struct v7
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The newest firmwares provide STA info using v7 of the struct. As v7
+isn't backward compatible, a union is needed.
+
+Even though brcmfmac does not use any of the new info it's important to
+provide the proper struct buffer. Without this change new firmwares will
+fallback to the very limited v3 instead of something in between such as
+v4.
