Add the dwc3 usb needed node information for rk3399.

Signed-off-by: Brian Norris <briannorris at chromium.org>

Somewhat rewritten from Caesar's reposting (v2) of my patch.

Changes:
 * Include USB2 PHY (which is now in -next)
 * Don't include USB3 PHY, as extcon support is not ready yet
 * Drop non-upstream properties
 * Fixup whitespace a bit
