boards: sam4s_xplained: Changed the sample to use USB on debug port 



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.

The ATSAM4S16C MCU has 2 UARTs and 2 USARTs. One of the UARTs (UART0) is

connected to the Segger J-Link OB chip (the AT91SAM3U4 is programmed to be

Segger J-Link OB). Segger J-Link OB brings the UART out as a virtual COM port.

The section flashing uses the UART from the Segger USB debug connection.
