Removed old hack of using Configuration Table entry ticks_per_timeslice

being set to 0 to indicate that there should be no Clock Tick.  This
was used by the Timing Tests to avoid clock tick overhead perturbing
execution times.  Now the Timing Tests simply leave the Clock Tick
Driver out of the Device Driver Table.
