[PATCH v3 15/15] arm64: dts: qcom: agatti: Add OPE node

[Loic Poulain <loic.poulain@oss.qualcomm.com>]

Add the Offline Processing Engine (OPE) device tree node for the
Agatti platform (QCM2290). The node describes the five register
regions (top, bus_read, bus_write, pipeline, qos), clocks, interrupt,
interconnects, IOMMU mappings, and OPP table.
