Subject: [PATCH v7 5/5] arm64: dts: rockchip: add USB support to rk3308.dtsi

From: Tobias Schramm <t.schramm@...jaro.org>

The Rockchip RK3308 features an integrated USB 2.0 phy, an USB OTG
controller and OHCI/EHCI interfaces.
This patch adds all of those to the RK3308 dtsi and thereby enables USB
support on the RK3308.
