Allow an irqdomain callback to report firmware-provided information
that is otherwise not available in a generic way. This is reported
using a new data structure (struct irq_fwspec_info).

This callback is optional and the only information that can be
reported currently is the affinity of an interrupt. However, the
containing structure is designed to be extensible, allowing other
potentially relevant information to be reported in the future.

Not aligning with what is in the structure that I can see.

Ah crap, I missed that one. I'll stash another fix for the next
version.

Thanks,
