The K3 AM62x family of SoC has one PRUSS-M instance and it has two Programmable Real-Time Units (PRU0 and PRU1). This does not support Industrial Communications Subsystem features like Ethernet.

Enhance the existing PRU remoteproc driver to support the PRU cores by using specific compatibles. The initial names for the firmware images for each PRU core are retrieved from DT nodes, and can be adjusted through sysfs if required.
