Commit dacf281771a9 ("w5100: remove unused gpio link detection")
dropped the link_gpio/link_irq handling on the grounds that no
devicetree user passed a "link" GPIO at the time.
This isn't a plain revert of that removal. The link GPIO is now
bound from the device tree link-gpios property using the resource
managed GPIO descriptors.
The link IRQ is also requested with devm_request_threaded_irq()
instead of request_any_context_irq(), so it is released automatically
on driver removal or probe failure.
