OMAP3 zoom1 Add usbtty configuration

The primary console of zoom1 is the serial out from the jumpers
accessed by removing the back panel.

A secondary console is to use the usbtty.  The user can set this
manually by doing

setenv stdout usbtty; setenv stdin usbtty; setenv stderr usbtty
saveenv

usbtty will be usable by accessing the /dev/ttyACM0 on a linux host.
