Subject: [PATCH 5.4 182/453] arm64: dts: rockchip: Set dr_mode to "host" for OTG on rk3328-roc-cc

From: Chen-Yu Tsai <wens@...e.org>

[ Upstream commit 4076a007bd0f6171434bdb119a0b8797749b0502 ]

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.
