[Qemu-devel] [PATCH v2 16/19] spapr: introduce a spapr_icp_create() helper

["Cédric Le Goater" <clg@kaod.org>]

On sPAPR, the creation of the interrupt presenter depends on some of
the machine attributes. When the XIVE exploitation interrupt mode is
available, this will get more complex. So provide a machine-level
helper to isolate the process and hide the details to the sPAPR core
realize function.
