Subject: [PATCH v5 18/19] dt-bindings: usb: qcom,dwc3: Validate DWC3 sub-node
Qualcomm msm8996/sc7180/sdm845 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 v2:
- Discard the "^dwc3@[0-9a-f]+$" nodes from being acceptable as sub-nodes.
