[PATCH 2/6] new timeofday i386 arch specific changes, part 1 for-mm (v.B3)

[john stultz]

Andrew, All,
	To hopefully improve the review-ability of my changes, I've split up my
arch-i386 patch into four chunks. This patch is just a simple cleanup
for the i386 arch in preparation of moving the the new timeofday
infrastructure. It simply moves some code from timer_pit.c to i8259.c.
	
It applies on top of my timeofday-core_B3 patch. This patch is part the
timeofday-arch-i386 patchset, so without the following parts it is not
expected to compile (although just this one should).
	
Andrew, please consider for inclusion for testing into your tree.

thanks
-john
