Remove CLOCK_TICK_RATE from tsc code

The tsc code uses CLOCK_TICK_RATE which on x86 is defined to just be the same as PIT_TICK_RATE. This patch updates the code use the later as we want to depecrate and remove the global CLOCK_TICK_RATE symbol.

1.7.4.1

So the ACTHZ issue is still at large (ie: we still want to have a better sense of the actual HZ frequency for the jiffies clocksource, since the irq generators will have some - possibly significant - granularity error), but I'm fine with these cases of just using PIT_TICK_RATE or PIT_LATCH on x86.

I've applied these four to my tree.
