The HVC_OPAL/RTAS/UDBG/XEN options are all bool, and hence their support is either present or absent. It will never be modular, so using module_init as an alias for __initcall is rather misleading.
Fix this up now, so that we can relocate module_init from init.h into module.h in the future. If we don't do this, we'd have to add module.h to obviously non-modular code, and that would be a worse thing. Note that direct use of __initcall is discouraged, vs. one of the priority categorized subgroups. As __initcall gets mapped onto device_initcall, our use of device_initcall directly in this change means that the runtime impact is zero -- it will remain at level 6 in initcall ordering. Also the __exitcall functions have been outright deleted since they are only ever of interest to UML, and UML will never be using any of this code.
