i8253: Create common clockevent implementation
...
arm, mips and x86 implement i8253 based clockevents. All the same code
copied. Create a common implementation in drivers/clocksource/i8253.c.
About time to rename drivers/clocksource/ to something else.

i8253: Move remaining content and delete asm/i8253.h
...
Move setup_pit_timer() declaration to the common header file and
remove the arch specific ones.
[ tglx: Move it to linux/i8253.h instead of asm/mips and asm/x86 ]

i8253: Consolidate definitions of PIT_LATCH
...
x86 defines PIT_LATCH as LATCH which in <linux/timex.h> is defined as
((CLOCK_TICK_RATE + HZ/2) / HZ) and <asm/timex.h> again defines
CLOCK_TICK_RATE as PIT_TICK_RATE.
MIPS defines PIT_LATCH as LATCH which in <linux/timex.h> is defined as
((CLOCK_TICK_RATE + HZ/2) / HZ) and <asm/timex.h> again defines
CLOCK_TICK_RATE as 1193182.
ARM defines PITCH_LATCH as ((PIT_TICK_RATE + HZ / 2) / HZ) - and that's
the sanest thing and equivalent to above definitions so use that as the
new definition in <linux/i8253.h>.
