Subject: [PATCH RFC v3 6/6] arm: dts: marvell: armada-388-clearfog: add
 description for usb phys

armada-38x.dtsi now has usb phy nodes for all 3 usb-2.0 ports.

Enable, and add references to the usb phys used by clearfog base and pro.
Explicitly set dr_mode to avoid phy driver warning messages during boot.

Finally replace the usb@...00 and usb3@...00 nodes with references to
labels in armada-38x.dtsi.
