The old configuration files did not work because of a missing
'at91sam9260minimal.cfg' file. Also, the config files were placed
wrongly. Update them, put them to the proper location, merge the two
supported boards into one, remove now superfluous include, remove
defunct web page, etc.. Tested with a Calao USB-A9G20 and a hacked
'device_desc' to match. Native support for it will come next.
