Revert "timecounter: No _Timecounter_Tick_simple() for SMP"
This reverts commit 46ae1d7a2b49b8f973dd6ba44fbbd38383798524.
The _Timecounter_Tick_simple() function actually doesn't switch to the
next timehand, so it is all right to use the simple timecounter approach
even on SMP configurations. The use of simple timecounters is not
recommended however since they impose a performance penalty.
