Should the call to irq_set_vcpu_affinity() fail at map time,
we should restore the normal lazy-disable behaviour instead
of staying with the eager disable that GICv4 requires.

gcc-4.5 and earlier don't like named initializers for anonymous
union members:

drivers/irqchip/irq-gic-v4.c:208:3: error: initialization makes pointer from integer without a cast
This is fairly easy to work around, by using extra curly braces.

When creating a VM, it is very convenient to have an irq domain
containing all the doorbell interrupts associated with that VM
(each interrupt representing a VPE).
