spapr: add hotplug hooks for PHB hotplug

Browse source 
Hotplugging PHBs is a machine-level operation, but PHBs reside on the
main system bus, so we register spapr machine as the handler for the
main system bus.

Provide the usual pre-plug, plug and unplug-request handlers.

Move the checking of the PHB index to the pre-plug handler. It is okay
to do that and assert in the realize function because the pre-plug
handler is always called, even for the oldest machine types we support.
