On RB5 it is 'typec:port0', as the USB-C port is registered as /sys/class/typec/port0 As with the other patch, I'm okay with this going through the USB tree.

Set the bridge's path property to point out that this connector is wrapped into the Type-C port. We can not really identify the exact Type-C port because it is registered separately, by another driver, which is not mandatory and the corresponding device is not even present on some of platforms, like sc8180x or sm8350. Thus we use the shortened version of the PATH, which includes just the 'typec:' part.
