[PATCH 2/2] arm64: dts: rockchip: enable usb2 for RK3328 evaluation board

[William Wu]

Rockchip's RK3328 evaluation board has one usb2 otg controller
and one usb2 host controller which consist of EHCI and OHCI.
Each usb controller connects with one usb2 phy port through
UTMI+ interface. Let's enable them to support usb2 on RK3328
evaluation board.
