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.
