Ok, from what I've seen :
- nit: interrupt.h not needed at early stage in vfio_platform_private.h,
until irq introduction
This cannot be fixed by a follow-on patch as it is just the order in

We can definitely decide at run-time whether to use the GIC and timers
or not, and the extra code and data structures that we allocate space
for is really negligable with this config option, so I don't think it's
worth the extra complexity of always having to define stub static
