[1/3] usb: dwc3: of-simple: Add compatible for rk3328

Commit Message

[e-mail] Aug. 16, 2020, 7:12 p.m. UTC

From: Cameron Nemo <[e-mail]>

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 commpatible with newer kernels.
