usb: dwc3: exynos: add support for exynos7870 



Exynos7870 devices have a DWC3 compatible USB 2.0 controller.
Add support in the driver by:
 - Adding its own compatible string, "samsung,exynos7870-dwusb3".
 - Adding three USBDRD clocks named "bus_early", "ref", and "ctrl", to
   be controlled by the driver.
