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.

Are there really only 2 32bit registers to control this h/w?

Superflous indentation after 'reg = ' and 'reg-names = '.
