genirq: Fix percpu_devid irq affinity documentation



Stephen points out that some of the percpu_devid irq affinity
documentation is either missing or not matching the data structures.

Address all the issues in one go.

Fixes: 87b0031f ("irqdomain: Add firmware info reporting interface")
Fixes: 258e7d28 ("genirq: Add affinity to percpu_devid interrupt requests")
