remoteproc: pru: Add support for various PRU cores on K3 J721E SoCs
The K3 J721E family of SoCs have a revised version of the AM65x ICSSG IP and contains two instances of this newer ICSSG IP. Each ICSSG processor subsystem contains 2 primary PRU cores, 2 auxiliary PRU cores called RTUs, and 2 new auxiliary cores called Transmit PRUs (Tx_PRUs). Enhance the existing PRU remoteproc driver to support these new PRU and RTU cores by using specific compatibles. The cores have the same memory copying limitations as on AM65x, so reuses the custom memcpy function within the driver's ELF loader implementation. The initial names for the firmware images for each PRU core are retrieved from DT nodes, and can be adjusted through sysfs if required.
