Allow multiple cpus in irq affinity call

Hi,

The generic irq affinity code limits us to a single cpu target regardless
of what the architecture supports. If required this should be done in
the architecture specific ->set_affinity call.

With this patch ppc64 is able to select all cpus affinity again.
