The only reason is to do with "how we present *SCHED_CLOCK options"?

If we make the *SCHED_CLOCK options default without prompts, then we do
not need a menu. These options can be selected at platform level
Kconfigs. We could possible cleanup the existing prompts.


Make *SCHED_CLOCK option as a prompt then we do need a menu as these
prompts appear randomly in the menuconfig.

Am happy with either approach.
