[PATCH 1/5] usb: dwc2: Add support for Canaan K230

[Junhui Liu]

Canaan Kendryte K230 SoC instantiates a dwc2 v4.30a core. This patch
adds the compatible for it.

The USB function on K230 currently relies on patch [1], which updates
the core reset flow of dwc2 in version 4.20a and newer. However, the USB
PHY drivers is not supported for now, and that will be a separate patch.
