[PATCH v2 2/2] ARM: dts: rockchip: enable usb for rk3229 evb board

[William Wu]

Rockchip's rk3229 evaluation board has one usb otg controller
and three usb host controllers. Each usb controller connect
with one usb2 phy port through UTMI+ interface. And the three
usb host interfaces use the same GPIO VBUS drive. Let's enable
them to support usb on rk3229 evb board.
