serial: ns16550: Move serial registration from serial_initialize()
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.
