[PATCH 10/20] dt-bindings: usb: dwc3: Add interrupt-names property support

[Serge Semin]

The controller driver supports two types of DWC USB3 devices: with a
common interrupt lane and with individual interrupts for each mode. Add
support for both these cases to the DWC USB3 DT schema.

Signed-off-by: Serge Semin <Sergey.Semin at baikalelectronics.ru>

Changelog v2:

- Drop quotes from around the string constants.
