This patch enables usb3_peri0 that uses usb3_phy0 to enable VBUS
detection for the USB3.0 peripheral.
The Salvator-X[S] has USB3.0 type-A connector and supplies VBUS
if USB3.0 host runs. So, you need a special cable for it, and
to stop the VBUS supplies from the board, after you installs
a gadget driver, you should run the following command to avoid
conflict VBUS supply:
# echo 1 > /sys/kernel/debug/ee020000.usb/b_device
