mac80211: brcmfmac: add early (& hacky) patch for storing 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.

+Subject: [PATCH] brcmfmac: add in-driver tables with country codes
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This adds early support for changing region. Ideally this data should
+be stored in DT as all these mappings are devices specific.
