Subject: [RFC PATCH v1 07/12] soc: qcom: pmic_glink_altmode: report that this is a Type-C connector

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.
