From: Greg Kurz <groug@kaod.org>

The realization of KVM ICP currently follows the parent_realize logic,
which is a bit overkill here. Also we want to get rid of the KVM ICP
class. Explicitely call icp_kvm_realize() from the base ICP realize
function.

Note that ICPStateClass::parent_realize is retained because powernv
needs it.
