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. Prepare i8253.h to be shared with x8664 Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Chris Wright <chrisw@sous-sol.org> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Arjan van de Ven <arjan@linux.intel.com>
