The rk3399 uses the innosilicon usb2 phy and the binding we've come up for
it looks a lot different than the above. So I'm not sure where this is
coming from, especially as I haven't seen the driver part for the rk3399 at
all yet. So far Frank was always working on te rk3366 variant, which seemed
to be the most complete.
