Replace the indirect function calls in the timer code
with direct calls to the newly added legacy_timer_tick()
helper for those that have not yet been converted to
generic clockevents.

This makes the timer code a little more self-contained.

I tested this series on a couple of different ColdFire parts
(5208 and 5475) and under QEMU emulating the 5208. All checked
out good, all worked as expected. So for the ColdFire changes:
