Subject: [PATCH] ARM: dts: msm: Add RM(Resource Manager) device for the
 trusted VM

Add RM device node to probe RM driver to initialize various hypervisor
resources like doorbell and message queues. This node should overlay by
RM-VM dynamically when the primary vm load the VM image into memory.
Until this support is ready in RMVM, statically maintain the node
information in the DT.
