There was already a CONFIG_ option for this feature but the code
performing timestamping simply ignored that.

The committed fix solves the problem well.

I think your idea is great in order to protect against similar
problems in the future, if TSC are expected to be used more and more.

All boards except bifferos/bifferboard and emulation/qemu-x86 have

select CPU_

in their Kconfig, so select TSC could be done in the CPU Kconfig
