[PATCH] arm64: dts: rockchip: support the usb2phy for rk3399 evb

[Caesar Wang <wxt-TNX95d0MmH7DzftRWevZcw@public.gmane.org>]

From: Frank Wang <frank.wang-TNX95d0MmH7DzftRWevZcw@public.gmane.org>

This patch adds the usb2phy needed dts node information for rk3399.

USB2.0 PHY is comprised of one Host port and one OTG port.
Host Port is for USB2.0 host controller; OTG port is for USB2.0 part of
USB3.0 OTG controller, and as a part to construct a fully feature TypeC
subsystem.

The USB2.0 vbus gpio is board specific, it's no same with all rk3399
boards, so move it into evb voard.
