While the timesync protocol was a great idea, it never ended up getting implemented by any known hardware devices. It's also a bit "interesting" in how it ties into the platform controller. So, just remove it for now. It's not needed, no one uses it, and it's a stumbling block in getting the greybus core code merged out of the staging tree. If anyone wants it in the future, reverting this patch is a great place to start from.
