dt-bindings: sram: qcom,imem: Allow modem-tables subnode
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.
