[PATCH 13/13] arm64: dts: exynos: exynos7885-jackpotlte: Enable USB support

The Samsung Galaxy A8 (2018) has an USB-C port capable of USB 2.0
speeds, used both as host and device, and is used for charging the
phone.

The physical port is directly connected to an S2MU004 IC, but until we
have support for it, we can still use the USB device funtionality.
