As there is no real dependency on it, remove the OF dependency from the

Yes, you're right.
But

No need to convert the value with cpu_to_leXX()/leXX_to_cpu()

This function adds an affinity parameter to irq_create_mapping().
This parameter is needed to pass it to irq_domain_alloc_descs().
irq_create_mapping() is a wrapper around irq_create_mapping_affinity()
to pass NULL for the affinity parameter.
No functional change.
