Subject: [PATCH v3] dt-bindings: usb: dwc3: Allow connector in USB controller node

Allow specifying the connector directly in the USB controller node, as
allow in other USB controller bindings and commonly used for
"gpio-usb-b-connector". Linux already supports this without driver
changes.

Changes in v3:
- Rebased onto linux-next (moved to the new snps,dwc3-common.yaml)
- Extended commit message
- Pull patch out of "TQ-Systems TQMa62xx SoM and MBa62xx board" series,
  as the series will need some more rework, and this patch should be
  good to go independently (and should go through the USB tree, unlike
  the rest of the series)
  In the submissions of the previous versions, the linux-usb list was
  forgotten by accident.

Changes in v2:
- Collected ack
- Rebased onto v6.13-rc1
