Some Texas Instruments K3 family of SoCs have one of more newer generation TMS320C71x CorePac processor subsystem in addition to the existing TMS320C66x CorePac processor subsystems. Update the device tree bindings document for the C71x DSP devices. The example is also updated to show the single C71 DSP present on J721E SoCs.
