The link interrupt is used for way more than just the link status; it comes from a collection of units to do with the port. The Marvell documentation describes the interrupt as "GOP port X interrupt". Since we are adding PTP support, and the PTP interrupt uses this, rename it to be more inline with the documentation. This interrupt is also mis-named in the DT binding, but we leave that alone.
