Do you mean removing all of the above is a pipedream, or using Kconfig like that?

I know we can't kill all of them, but there are still a few in the list above
that can be made to use clocksource, and I'm fine with keeping the list
around for the ones that really can't. The comment should probably be
clearer, but it was more intended for people with random out-of-tree platform
code that should be converted to use clocksource.
