The IP Accelerator hardware/firmware owns a sizeable region within the IMEM, named 'modem-tables', containing various packet processing configuration data. It's not actually accessed by the OS, although we have to IOMMU-map it with the IPA device, so that presumably the firmware can act upon it. Allow it as a subnode of IMEM.
