Revert "clockevents: Add a clkevt-of mechanism like clksrc-of"
After discussing it, this feature is dropped as it is not considered
adequate:
https://patchwork.kernel.org/patch/9639317/
There is no user of this macro yet, so there is no impact on the drivers.
This reverts commit 376bc27150f180d9f5eddec6a14117780177589d.
