[PATCH v2 3/5] dt-bindings: phy: rockchip,inno-usb2phy: Add compatible for RK3528

[Heiko Stuebner]

From: Jonas Karlman <jonas@xxxxxxxxx>

The embedded USB2 PHY on RK3528 is very similar to the one in RK3568,
the main difference being that it only uses two clocks instead of three.

Add compatible to support the USB2 PHY in RK3528.
