TVWS 19.07

for Riot albatross TVWS devices

• ATH79 branch ( not ar71xx anymore ) using devicetree
• ar93xx devicetree has fixes for GPIO pins multiplexing
• patches removed that caused network instability ( see commit c7fcaf6
• Ethernet connection is now named ETH1 - so an upgrade from an older "eth0" named device is not smooth

don't keep settings if upgrading form an older device ( -n flag or check the box during web upgrade )

flash using web interface or scp to the device /tmp folder and run
'' sysupgrade -v -n -F /tmp/openwrt* "

includes nano, batman-adv and batctl 2019.3, mixer control, tvws-luci and gpsd
