serial: arm: Implement CONFIG_SERIAL_MULTI into atmel serial driver

Implement support for CONFIG_SERIAL_MULTI into atmel serial driver.
This driver was so far only usable directly, but this patch also adds
support for the multi method. This allows using more than one serial
driver alongside the atmel driver. Also, add a weak implementation
of default_serial_console() returning this driver.
