usb: typec: mux: avoid duplicated mux switches
Some devices use combo PHYs (i.e. USB3 + DisplayPort), which also
handle the lane muxing. These PHYs are referenced twice from
the USB-C connector (USB super-speed lines and SBU/AUX lines)
resulting in the mux being configured twice. Avoid this by
dropping duplicates.
This is a re-application of b145c3f29d62 ("usb: typec: mux: avoid
duplicated mux switches"), with fix derived from usb: typec: mux:
Fix typec_switch_match() .
