The common J7 specific start_non_linux_remote_cores() override function implements the logic to load and boot the Main R5FSS Core0 from R5 SPL. This won't be supported any more for either J721E or J7200 after the R5 SPL rearchitecture for the System Firmware split into TI Foundation Security (TIFS) and Device Management (DM) firmwares. So, cleanup the corresponding code and the related SPL env variables.
