arm64: dts: exynos990: Add USB nodes
Add USB controller and USB PHY controller nodes for use in
the Exynos990 SoC.
This SoC supports USB full-speed, high-speed and super-speed modes.
Due to the inability to test PIPE3, USB super-speed is not enabled, and
the USB PHY is only configured for UTMI+ operation for now.
