Remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. In doing so, da9052_device_exit() becomes orphaned, so it gets removed as well. 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 was not in use by this code, the init ordering remains unchanged with this commit. We replace module.h with init.h where required, i.e. if the the file did not include that already. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the files in the comments.
