Implement DisplayPort support for the Qualcomm RB5 platform.
Note: while testing this, I had link training issues with several
dongles with DP connectors. Other DisplayPort-USB-C dongles (with HDMI
or VGA connectors) work perfectly.

Supporting DP/USB-C can result in a chain of several transparent
bridges (PHY, redrivers, mux, etc). This results in drivers having
similar boilerplate code for such bridges.
Next, these drivers are susceptible to -EPROBE_DEFER loops: the next
bridge can either be probed from the bridge->attach ca
Define a helper for creating simple transparent bridges which serve the
only purpose of linking devices into the bridge chain up to the last
bridge representing the connector. This is especially useful for
DP/USB-C bridge chains, which can span across several devices, but do
not require any additio
