serial: pxa: make it explicitly non-modular
The Kconfig currently controlling compilation of this code is: drivers/tty/serial/Kconfig:config SERIAL_PXA drivers/tty/serial/Kconfig: bool "PXA 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. We 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. Since module_init translates to device_initcall in the non-modular case, the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE and MODULE_ALIAS are both a no-op for non-modular builds. We also delete the MODULE_LICENSE tag since that information is already contained at the top of the file in the comments.
