Oops, the EHCI and OHCI controllers on exynos5440 do not need any explicit
phy configuration.
So need to assign a different compatible value for these controllers...

If no problem, let me take this patch into samsung tree with fix.

+		compatible = "samsung,exynos5440-ohci";

Same as above.

+		compatible = "samsung,exynos5440-ehci";
