Vladimir Murzin ce87122911 serial: mps2-uart: make driver explicitly non-modular
The Kconfig currently controlling compilation of mps2-uart is:

config SERIAL_MPS2_UART
	bool "MPS2 UART port"
	depends on ARM || COMPILE_TEST

...meaning that it currently is not being built as a module by anyone.

Follow commit 89ebc2742769 ("drivers/tty: make serial/mvebu-uart.c
explicitly non-modular") as an example of moving modular code to
non-modular:

- remove the modular code that is essentially orphaned, so that
  when reading the driver there is no doubt it is builtin-only.

- explicitly disallow a driver unbind, since that doesn't have a
  sensible use case anyway, and it allows us to drop the ".remove"
  code for non-modular drivers.

- use arch_initcall instead of module_init and remove module_exit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE tag etc. since all that information
was (or is now) contained at the top of the file in the comments.
