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

Browse Source 
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.
