When the core is integrated with glue, it's reasonable to assume that the glue driver will have to touch the IP before/after the core takes the hardware out and into reset. As such the glue must own these resources and be allowed to turn them on/off outside the core's handling. Allow the platform or glue layer to indicate if the core logic for clocks and resets should be skipped to deal with this.
