This SYSC register has also very unique bit-fields. Both the IPs require the PRCM reset to be deasserted to be able to access any registers. Add a common PRUSS interconnect target-module with all the required properties. The PRUSS devices themselves shall be added as child nodes to this interconnect node in the future. The PRU-ICSS instances are not supported on AM4372 SoC though in the AM437x family, so the target module node should be enabled in only those derivative board files that use a SoC containing the PRU-ICSS IPs.
