[PATCH 1/3] arm64: dts: rockchip: rk3328-roc-cc: Set dr_mode to "host" for OTG

From: Chen-Yu Tsai <wens at csie.org>

The board has a standard USB A female port connected to the USB OTG
controller's data pins. Set dr_mode in the OTG controller node to
indicate this usage, instead of having the implementation guess.
