From: Hari Nagalla <hnagalla at ti.com>

The K3 J784S4 SoCs have 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 slighly 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.
