It's abstract, derived directly from TYPE_OBJECT (to avoid dependency
on MODULE_INIT_DEVICE) and for now is empty.
Place it in hw/. Have user emulators pick it up via VPATH, building it
per target since they didn't use any qdev/QOM devices so far.
Introduce processor_init() for registering, and call module init as
needed.
