usb: typec: Add Displayport Alternate Mode 2.1 Support
Displayport Alternate mode 2.1 requires configuration for additional
cable details such as signalling for cable, UHBR13.5 Support, Cable type
and DPAM version.
These details can be used with mux drivers to configure SOP DP
configuration for Displayport Alternate mode 2.1.
This change also includes pertinent cable signalling support in displayport
alternate mode.
