This results in a link error on configurations that use a modular OHCI code on this platform. While the proper solution for this problem would be to implement a real PHY driver shared by ohci-da8xx and musb-da8xx, this patch for now just works around the build error by only allowing the ohci-da8xx code to be built-in.
