In the root node the Integrator/CP must have a /cpcon node pointing
to the CP control registers, and the Integrator/AP must have a
/syscon node pointing to the Integrator/AP system controller.
+The AP syscon node must include the logic module interrupts, stated

The OF/DT boot path needs to get the LM (Logical Module) IRQs from the device tree for coherency. This augments the DT syscon node to contain these IRQs and alter the DT LM code to get them from there.
