I've seen at least one driver which configures interrupts in
config_init and doesn't define a config_intr callback
(ack_interrupt callback is there)
Intention of this check is not to ensure that the driver defines
everything to make interrupts work. All it states:
If at least one of the irq-related callbacks is defined, then
we interpret this as indicator that the PHY supports interrupts.
