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.

Hi Cameron,

Use plain text mode for patches.

Before you introduce a new compatible string, your patch serie must
change the documents first in version 2.
See:

dwc3.txt
rockchip,dwc3.txt

(TODO but not now) Both documents are in need for a conversion to yaml.

Also sort nodes without reg alphabetically in rk3328-rock64.dts.

&u2phy {}
&uart2 {}
&usb20_otg {}
&usbdrd3 {}
&usbdrd_dwc3 {}
&usb_host0_ehci {}
&usb_host0_ohci {}
