The IPs do not have any PRCM reset lines unlike those on AM33xx/AM437x SoCs. Add the PRUSS interconnect target-module nodes with all the required properties. Each of the PRUSS devices themselves shall be added as child nodes to the corresponding interconnect node in the future. The PRU-ICSS instances are only available on AM57xx family of SoCs and are not supported on DRA7xx family of SoCs in general, so the target module nodes are added in a separate dtsi file. This new dtsi file is included in all the AM57xx SoC dtsi files, so the nodes are automatically inherited and enabled on all AM57xx boards.
