Subject: [PATCH v2 2/6] arm64: dts: rockchip: support dwc3 USB for rk3399

Add the dwc3 usb needed node information for rk3399.

Signed-off-by: Brian Norris <briannorris@...omium.org>

Somewhat rewritten from Caesar's reposting (v2) of my patch.
Changes (?? -> v1):
 * 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

v1 -> v2:
 * add phy_type = "utmi_wide"
 * sort by unit address
 * match upstream clock names and delete unnecessary ones
