gpio: sodaville: make it explicitly non-modular
The Kconfig currently controlling compilation of this code is: drivers/gpio/Kconfig:config GPIO_SODAVILLE drivers/gpio/Kconfig: bool "Intel Sodaville GPIO 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_pci_driver() uses the same init level as the builtin_pci_driver() does, there is no init ordering change caused by this commit. We don't replace module.h with init.h since the file already has that. 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. Cc: Hans J.
