I removed them as currently the driver is being upstreamed only for AM654x,
once I start up-streaming the ICSSG driver for AM64 and any other SoC. I will
add them here. If at that time we are still using same compatible, then I will
modify the comment otherwise add new compatible.

As of now, I don't see the need of adding other SoCs in iep binding as IEP
driver up-streaming is only planned for AM654x as of now.
