[PATCH v2 1/5] arm64: dts: rockchip: Add USB nodes for RK3528

[Heiko Stuebner <heiko@sntech.de>]

From: Jonas Karlman <jonas@kwiboo.se>

Rockchip RK3528 has one USB 3.0 DWC3 controller and oneUSB 2.0 EHCI/OHCI
controller and uses an Innosilicon-USB2PHY for USB 2.0. The DWC3
controller additionally uses the Naneng Combo PHY for USB3.

Add device tree nodes to describe these USB controllers along with the
USB 2.0 PHYs.
