[RFC PATCH v2 17/20] hw/pci-host/gpex: Mark device with no migratable fields

[Philippe Mathieu-Daudé]

TYPE_GPEX_HOST does not have internal state to migrate.
Its only interesting state is in the GPEXRootState, which
is a TYPE_GPEX_ROOT_DEVICE which migrates itself.
Explicit there is nothing to migrate by using the special
vmstate_qdev_no_state_to_migrate.
