The K3 J784S4 SoC has four C71x DSP subsystems in MAIN voltage domain. The C71x DSPs are 64 bit machine with fixed and floating point DSP operations. The C71x DSP subsystem is a slightly updated version of the C71x DSP subsystem on J721E. And, same IP data can be used for J7200, J721S2 and J784S4.
Extend support to the C71x DSPs for J784S4 with J721S2 compatible string.
