Document bindings for the Parade PS8830 Type-C retimer. This retimer is
currently found on all boards featuring Qualcomm Snapdragon X Elite SoCs
and it is needed to provide altmode muxing between DP and USB, but also
connector orientation handling between.

Presumably all of the supplies are also required.
Similar for clocks, etc.

The reset line is active low.

Please add a newline before each child node for readability.

We typically avoid adding unused labels to the examples, but perhaps
here it serves as documentation?

Add newline here too, and similar below.
