xics: Handle KVM ICS reset from the "simple" ICS code

Browse Source 
The KVM ICS reset handler simply writes the ICS state to KVM. This
doesn't need the overkill parent_reset logic we have today. Also
we want to use the same ICS type for the KVM and non-KVM case with
pseries.

Call icp_set_kvm_state() from the "simple" ICS reset function.
