ca569e9bbe dt-bindings: remoteproc: k3-r5f: Update bindings for J7200 SoCs
The K3 J7200 SoCs have two dual-core Arm R5F clusters/subsystems, with
2 R5F cores each, one in each of the MCU and MAIN voltage domains.

These clusters are a revised version compared to those present on
J721E SoCs. Update the K3 R5F remoteproc bindings with the compatible
info relevant to these R5F clusters/subsystems on K3 J7200 SoCs.

471c2d5e22 dt-bindings: remoteproc: Add bindings for R5F subsystem on TI K3 SoCs
The Texas Instruments K3 family of SoCs have one of more dual-core
Arm Cortex R5F processor subsystems/clusters (R5FSS). Add the device
tree bindings document for these R5F subsystem devices. These R5F
processors do not have an MMU, and so require fixed memory carveout
regions matching the firmware image addresses. The nodes require more
than one memory region, with the first memory region used for DMA
allocations at runtime. The remaining memory regions are reserved
and are used for the loading and running of the R5F remote processors.

The added example illustrates the DT nodes for the single R5FSS device
present on K3 AM65x family of SoCs.
