pnv/psi: Add device reset hook
And call it from a QEMU reset handler. This allows each PNV child class to override the reset hook if needed, eg. POWER8 doesn't but POWER9 does. The proper way to do that would be to use device_class_set_parent_reset(), but defining a Pnv8PsiClass and a Pnv9PsiClass types with a parent_reset pointer adds a fair amount of code. Calling pnv_psi_reset() explicitely is fine for now. A subsequent patch will consolidate the call to qemu_register_reset() in a single place.
