Move the registration of serialN_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 mpc512x_serial_initialize() function, which is implemented inside of the mpc512x serial driver allows encapsulation of serialN_device within the mpc512x serial driver itself. Also, remove the exports of serialN_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 mpx512x serial driver and the default console is picked by CONFIG_SERIAL<N> macro in config file.
