Subject: [PATCH 2/5] 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.
