Some SOCs in the i.MX6 family have a USB host controller that is
only capable of the HSIC interface and has no on-board PHY.
To be able to use these controllers, we need to add "usb-nop-xceiv"
dummy PHYs.

Why #phy-cells property is needed? Others are ok for me.

From Documentation/devicetree/bindings/usb/usb-nop-xceiv.txt:
Required properties:
- compatible: should be usb-nop-xceiv
