For cases that wish to reserve a single IRQ simply provide a wrapper in to the ranged reservation routine.

I picked irq_reserve_irq() to follow the irq_alloc_descs/desc naming scheme, but perhaps irq_reserve() or irq_reserve_at() is less visually offensive? Feel free to mangle away as necessary :-)
