Add in a configuration file and hints for the Engenius ENH-200.

This is an AR7240 based device with an AR9285 on-board.

I've tested the initial boot and wifi support; however at the moment
the ethernet switch driver doesn't seem to be picking up carrier on the
active ethernet port. Basic flood pinging works however, so I think
we're on the right track.

Thank you to Adrian Woodley <adrian@diskworld.com.au> for purchasing me
one of these devices to bootstrap FreeBSD-HEAD on.
