[v5,19/19] dt-bindings: usb: intel,keembay-dwc3: Validate DWC3 sub-node

Intel Keem Bay DWC3 compatible DT nodes are supposed to have a DWC USB3
compatible sub-node to describe a fully functioning USB interface. Let's
use the available DWC USB3 DT schema to validate the Qualcomm DWC3
sub-nodes.

Note since the generic DWC USB3 DT node is supposed to be named as generic
USB HCD ("^usb(@.*)?") one we have to accordingly fix the sub-nodes name
regexp and fix the DT node example.

Changelog v5:
- This is a new patch created for the new Intel Keem Bay bindings file,
  which has been added just recently.
