xics: Link ICP_PROP_CPU property to ICPState::cs pointer

The ICP object has both a pointer and an ICP_PROP_CPU property pointing
to the cpu. Confusing bugs could arise if these ever go out of sync.

Change the property definition so that it explicitly sets the pointer.
The property isn't optional : not being able to set the link is a bug
and QEMU should rather abort than exit in this case.
