Seems we are using all three ports (including fsl_udc for debugging). I left 
them out because they seem to be switched on automaticly (either via the 
bootloader or via the tegra-ehci driver).

On the other hand, we want to move to u-boot sooner or later so I think it's 
better to enable them now.
