Commit Message

  Like on the CRD, add the necessary nodes to enable USB Type-C
altmode-based external display on the Lenovo ThinkPad X13s.

Signed-off-by: Bjorn Andersson <quic_bjorande@quicinc.com>

Changes since v2:
- Added empty line between properties and child nodes
- Use &usb_1_role_switch label from sc8280xp.dtsi
