Some boards with an onboard USB hub supported by the onboard_hub
driver have a device tree node for the hub, but the node doesn't
specify all properties needed by the driver (which is not a DT
error per se). For such a hub no onboard_hub platform device is
created. However the USB portion of the onboard hub driver still
probes and uses _find_onboard_hub() to find the platform device
that corresponds to the hub. If the DT node of the hub doesn't
have an associated platform device the function looks for a
"peer-hub" node (to get the platform device from there), if
that doesn't exist either it logs an error and returns -EINVAL.
The absence of a platform device is expected in some
configurations, so drop the error log and fail silently with
-ENODEV.
