gpio: zevio: make it explicitly non-modular
The Kconfig currently controlling compilation of this code is: drivers/gpio/Kconfig:config GPIO_ZEVIO drivers/gpio/Kconfig: bool "LSI ZEVIO SoC memory mapped 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. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. 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 is already contained at the top of the file in the comments.
