[PATCH 4/5] drivers/tty: make serial/mpsc.c driver explicitly non-modular

[Paul Gortmaker <paul.gortmaker@windriver.com>]

The Kconfig for this driver is currently:

config SERIAL_MPSC
        bool "Marvell MPSC serial port support"

...meaning that it currently is not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.

We leave some tags like MODULE_AUTHOR for documentation purposes.
