Implement support for CONFIG_SERIAL_MULTI into p3mx 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 p3mx driver. Also, add a weak implementation of default_serial_console() returning this driver.
