Create include/linux/module.h with stub definitions for kernel module
support. U-Boot doesn't use loadable modules, so these are no-ops.
Includes:
- THIS_MODULE, try_module_get(), module_put()
- module_init(), module_exit()
- module_param() and variants
- MODULE_* macros (LICENSE, AUTHOR, DESCRIPTION, etc.)
Update compat.h to include module.h and remove duplicate definitions.
