Some boards dont have gpios assigened for vbus or oci.
Allow these boards to enumerate usb without declaring the set_power

The usb20_phy clock needs to be registered for the driver to be able

To prepare for DT support we will remove the usb callback function
pointers. Since this structure will only pass data to the driver, It
seems better to rename the structure root_hub structure to platform_data
There is no functional change.

The phy framework requests an optional "phy" regulator. If it does
not find one, it returns -EPROBE_DEFER. In the case of non-DT based boot
