Move the registration of eserialN_device ports from default serial_initialize() into driver specific function called from serial_initialize(). This slims down the serial_initialize() call to a bare tracker of all possible serial port registration routines in U-Boot. The newly implemented ns16550_serial_initialize() function, which is implemented inside of the ns16550 serial driver allows encapsulation of eserialN_device within the ns16550 serial driver itself. Also, remove the exports of eserialN_device from include/serial.h as they are no longer needed. This is simply because the implementation of default_serial_console() is wrapped into the ns16550 serial driver and the default console is picked by CONFIG_SERIAL<N> macro in config file.
