drivers/serial/atmel_serial.c: fix compile when CONFIG_SERIAL_ATMEL=Y and CONFIG_SERIAL_ATMEL_CONSOLE=N

Browse source 
When SERIAL_ATMEL_CONSOLE is disabled, ATMEL_CONSOLE_DEVICE is set to
NULL, and trying to access ATMEL_CONSOLE_DEVICE->flags in
atmel_serial_probe makes the compile fail.  This fixes the issue by only
accessing it if CONFIG_SERIAL_ATMEL_CONSOLE is defined
