Marius Strobl 17f3c8f1e3 - In oneshot-mode it doesn't make sense to try to compensate the clock
drift in order to achieve a more stable clock as the tick intervals may
  vary in the first place. In fact I haven't seen this code kick in when
  in oneshot-mode so just skip it in that case.
- There's no need to explicitly stop the (S)TICK counter in oneshot-mode
  with every tick as it just won't trigger again with the (S)TICK compare
  register set to a value in the past (with a wrap-around once every ~195
  years of uptime at 1.5 GHz this isn't something we have to worry about
  in practice).
- Given that we'll disable interrupts completely anyway there's no
  need to enter critical sections.
