====================
Full phylink support for mv88e6352

These two patches implement full phylink support for the mv88e6352
family, when using an SFP connected to its SERDES interface. This adds
interrupt support to the SERDES, so that we get interrupts on link
up/down, and then make calls phydev_link_change().

The first patch is a minor bug fix, which does not seem to affect any
current features, so i'm not submitting it for stable. It is however
required for configuring SERDES interrupts.
