From: Greg Kurz <groug@kaod.org>

The proper way to do that would be to use device_class_set_parent_realize(),
but defining a Pnv8PsiClass and a Pnv9PsiClass types with a parent_realize
pointer adds a fair amount of code. Calling pnv_psi_realize() explicitely
is fine for now.

This should probably be achieved with a device realize hook in the
PSI base class and device_class_set_parent_realize() in the children
classes.
