tty: serial: Add Nuvoton ma35d1 serial driver support 



This adds UART and console driver for Nuvoton ma35d1 Soc.
It supports full-duplex communication, FIFO control, and
hardware flow control.
Command line set "console=ttyNVT0,115200", NVT means
Nuvoton MA35 UART port. The UART driver probe will
create path named "/dev/ttyNVTx".

	  This driver supports Nuvoton MA35D1 family UART ports. If you would

	  like to use them, you must answer Y or M to this option. Note that

	  for use as console, it must be included in kernel and not as a

	  module. If you enable this option, Ma35D1 serial ports in the system

	  will be registered as ttyNVTx.

	  Select this options if you'd like to use the UART port0 of the

	  Nuvoton MA35D1 family as a console.

	  Even if you say Y here, the currently visible virtual console

	  (/dev/tty0) will still be used as the system console by default,

	  but you can alter that using a kernel command line option such as

	  "console=ttyNVTx".
