While most boards meanwhile migrated to using binman a few like the verdin-imx8mm are still using the legacy image generation. Unfortunately, the legacy image generation is currently broken which is especially bad for any kind of bisection attempts. Anyway, this fixes it even though we will also migrate to using binman shortly.

Turns out Microship (formerly Micrel) meanwhile integrated proper support for the DLL setup on their KSZ9131. Unfortunately, this conflicts with our previous board code doing that. Fix this by getting rid of our board code and just relying on the generic implementation relying on rgmii-id being used as phy-mode.
