driver core: bus: constantify subsys_register() calls
The functions subsys_register() and subsys_virtual_register() should be
taking a constant pointer to a struct bus_type, as they do not actually
modify anything in it, so fix up the function definitions to do so
properly.
This also changes the pointer type in struct subsys_interface to be
constant as well, as again, that's the proper signature of it.
