[088/151] xen: register timer interrupt with IRQF_TIMER

From: Ian Campbell <ian.campbell@citrix.com>

commit f350c7922faad3397c98c81a9e5658f5a1ef0214 upstream.

Otherwise the timer is disabled by dpm_suspend_noirq() which in turn prevents
correct operation of stop_machine on multi-processor systems and breaks
suspend.
