xics: Handle KVM ICP reset from the common code 

The KVM ICP reset handler simply writes the ICP state to KVM. This
doesn't need the overkill parent_reset logic we have today. Call
icp_set_kvm_state() from the base ICP reset function instead.

Since there are no other users for ICPStateClass::parent_reset, and
it isn't currently expected to change, drop it as well.
