usb: typec: Add support for Parade PS8830 Type-C Retimer
The Parade PS8830 is a USB4, DisplayPort and Thunderbolt 4 retimer,
controlled over I2C. It usually sits between a USB/DisplayPort PHY
and the Type-C connector, and provides orientation and altmode handling.
The boards that use this retimer are the ones featuring the Qualcomm
Snapdragon X Elite SoCs.
Add a driver with support for the following modes:
- DisplayPort 4-lanes
- DisplayPort 2-lanes + USB3
- USB3
There is another variant of this retimer which is called PS8833. It seems
to be really similar to the PS8830, so future-proof this driver by
naming it ps883x.
