The IP also uses a hard-reset line, and requires this PRCM reset to be deasserted to be able to access any registers. Update the existing PRUSS interconnect target-module with all the required properties. The PRUSS device itself shall be added as a child node to this interconnect node in the future. PRU-ICSS is not supported on AM3352 SoC though in the AM33xx family, so the target module node should be enabled in only those derivative board files that use a SoC containing PRU-ICSS.
