The device structure used is not the one of the specific ChipIdea driver but the one of the generic ChipIdea platform device. This results in not being able to probe the PHYs as we're not using the right device structure. Since all ChipIdea drivers are retrieving their PHYs in their specific driver code, this didn't impact any of them yet. Fixes it using the right device structure (dev->parent).
