ppc/xics: rework the ICS classes inheritance tree 

With the previous changes, we can now let the ICS_KVM class inherit
directly from ICS_BASE class and not from the intermediate ICS_SIMPLE.
It makes the class hierarchy much cleaner.

What is left in the top classes is the low level interface to access
the KVM XICS device in ICS_KVM and the XICS emulating handlers in
ICS_SIMPLE.

This should not break migration compatibility.
