[PATCH 17/22] hw/acpi/ged: Call pcihp plug callbacks in hotplug handler implementation

[Eric Auger <eric.auger@redhat.com>]

Add PCI device related code in the TYPE_HOTPLUG_HANDLER
implementation.

For a PCI device hotplug/hotunplug event, the code routes to
acpi_pcihp_device callbacks (pre_plug_cb, plug_cb, unplug_request_cb,
unplug_cb).
