xen: xen_debug_interrupt prototype to global header

Browse source 
The xen_debug_interrupt() function is only called on x86, which has a
prototype in an architecture specific header, but the definition also
exists on others, where the lack of a prototype causes a W=1 warning:

drivers/xen/events/events_2l.c:264:13: error: no previous prototype for 'xen_debug_interrupt' [-Werror=missing-prototypes]

Move the prototype into a global header instead to avoid this warning.
