Changed the default UART used for the console. You used to have to
use wires on the J4 header. Now you can use the UART provided by the
Segger USB composite device.

We can use the chosen property "zephyr,console" to determine what uart
should be used as the console and find its name to generate a define for
CONFIG_UART_CONSOLE_ON_DEV_NAME.
