xen: use percpu interrupts for IPIs and VIRQs
commit aaca49642b92c8a57d3ca5029a5a94019c7af69f upstream.
IPIs and VIRQs are inherently per-cpu event types, so treat them as such:
- use a specific percpu irq_chip implementation, and
- handle them with handle_percpu_irq
This makes the path for delivering these interrupts more efficient
(no masking/unmasking, no locks), and it avoid problems with attempts
to migrate them.
