arm64: dts: qcom: x1e80100-t14s: Describe the Parade PS8830 retimers
The Lenovo ThinkPad T14s Gen6 laptop comes with 3 Parade PS8830 retimers, one for each Type-C port. These handle the orientation and altmode switching and are controlled over I2C. In the connection chain, they sit between the USB/DisplayPort combo PHY and the Type-C connector. Describe the retimers and all gpio controlled voltage regulators used by each retimer. Also, modify the pmic glink graph to include the retimers in between the SuperSpeed/Sideband in endpoints and the QMP PHY out endpoints.
