Hi, Keir,

If we don't use PIT, we should disable it at boot time and at S3
resuming. In Xen this is done by disable_pit_irq(), but this function is
used by __initcall(). After bootstrap it will be discarded and may be
overwritten. This usually results in S3 resuming failure. This patch
fixed the issue.
