i386: prepare sharing the PIT code
PIT clock events work already and the PIT handling is the same for
i386 and x86_64. x86_64 does not support PIT as a clock source, so
disable the PIT clocksource for x86_64.
Use the i386 i8253.h include file for x86_64 as well to share the
exports and the PIT constants.
