Add the Offline Processing Engine (OPE) device tree node for the Agatti platform (QCM2290). The node describes the six register regions (cdm, top, qos, pipeline, bus_read, bus_write), clocks, interrupt, interconnects, IOMMU mappings, and OPP table. OPE is a memory-to-memory block with no board-level dependencies, so the node is left enabled for all Agatti boards.
