gpio: stmpe: make it explicitly non-modular
The Kconfig currently controlling compilation of this code is:
drivers/gpio/Kconfig:config GPIO_STMPE
drivers/gpio/Kconfig: bool "STMPE GPIOs"
...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.
Curiously, this driver was using subsys_initcall since day one, so
we don't have the "normal" module_init replacement in this change
like we've done in other similar driver updates.
We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.
