profiling: Remove unused timer hook

Browse source 
The last remaining user was oprofile and its use has been
removed a while ago in commit bc078e4eab
("oprofile: convert oprofile from timer_hook to hrtimer").

There doesn't seem to be any upstream user of this hook
for about two years now. And I'm not even aware of any out of
tree user.

Let's remove it.
