s390: virtio: make ccw explicitly non-modular
The Kconfig currently controlling compilation of this code is: arch/s390/Kconfig:config S390_GUEST arch/s390/Kconfig: def_bool y ...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. Since module_init translates to device_initcall in the non-modular case, the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We replace module.h with moduleparam.h since the file does declare some module_param() and leaving that as-is is currently the easiest way to remain compatible with existing boot arg use cases.
