Subject: [PATCH v4 2/4] usb: dwc3: of-simple: Add compatible for rk3328

From: Cameron Nemo <cnemo@...anota.com>

Add a compatible to be hooked into by the Rockchip rk3328 device tree.

The rk3399 compatible cannot be reused because the rk3328 SoCs may
require a specialized driver in the future, and old device trees must
remain compatible with newer kernels.
