Subject: [PATCH 07/13] ARM: STi: DT: STiH407: Add usb2 picophy dt nodes

This patch adds the dt nodes for the usb2 picophy found on the stih407
family of devices. It is used on stih410 and later devices with the ehci/ohci usb
controller, and is also used as the usb2 phy with the dwc3 usb3 controller.
