Use the generic PHY API instead of the platform callback to control
the DP PHY. The 'phy_label' field is added to the platform data
structure to allow PHY lookup on non-dt platforms.

I've an issue here you break dt compatibilty
Indeed. Ideally the PHYs should be detachable from the controllers.
I'd assume such a change could be acceptable, given that the driver
still supports the original binding.
