usb: phy: add a new driver for usb3 phy
Added a driver for usb3 phy that handles the interaction between usb phy
device and dwc3 controller.
This also includes device tree support for usb3 phy driver and
the documentation with device tree binding information is updated.
Currently writing to control module register is taken care in this
driver which will be removed once the control module driver is in place.
