dt-bindings: usb: dwc3: Move Amlogic G12A DWC3 Glue Bindings to YAML …
…schemas Now that we have the DT validation in place, let's convert the device tree bindings for the Amlogic G12A DWC3 Glue Bindings over to a YAML schemas, the AXG and GXL glue bindings will be converted later.

| description: | | ||
| The Amlogic G12A embeds a DWC3 USB IP Core configured for USB2 and USB3 | ||
| in host-only mode, and a DWC2 IP Core configured for USB2 peripheral mode | ||
| only. | ||
| A glue connects the DWC3 core to USB2 PHYs and optionally to an USB3 PHY. | ||
| One of the USB2 PHYs can be re-routed in peripheral mode to a DWC2 USB IP. | ||
| The DWC3 Glue controls the PHY routing and power, an interrupt line is | ||
| connected to the Glue to serve as OTG ID change detection. | ||
