x86/init: Add intr_mode_init to x86_init_ops
X86 and XEN initialize interrupt delivery mode in different way.
To avoid conditionals, add a new x86_init_ops function which defaults to
the standard function and can be overridden by the early XEN platform code.
[ tglx: Folded the XEN part which was a separate patch to preserve
bisectability ]
