From: Konrad Dybcio <konrad.dybcio@oss.qualcomm.com>

The IP Accelerator hardware/firmware owns a sizeable region within the
IMEM, ominously named 'modem-tables', presumably having to do with some
internal IPA-modem specifics.

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.
