genirq: Update stale comment for __irq_domain_add

Commit 1bf4ddc46c ("irqdomain: Introduce irq_domain_create_{linear,
tree}") introduced the use of fwnode_handle to identify the interrupt
controller when calling __irq_domain_add but missed updating the kernel
doc parameters for the function.

Update this comment. While we are touching this code, also consolidate
the declaration and assignment of of_node.
