arm: dts: rockchip: rk3399-roc-pc: Enable FE1.1 USB 2.0 HUB on roc-rk3399-pc

Browse source 
roc-rk3399-pc has an FE1.1 USB 2.0 HUB which connects two USB ports
(HOST1 and HOST2). For end devices to work we need to enable USB hub
so that HOST detects there presence and enumerates them accordingly.
This requires explicit pinctrl within gpio enablement.
