usb: ucsi: glink: use the connector orientation GPIO to provide switch events

[ Upstream commit c6165ed2f425c273244191930a47c8be23bc51bd ]

On SM8550, the non-altmode orientation is not given anymore within
altmode events, even with USB SVIDs events.

On the other side, the Type-C connector orientation is correctly
reported by a signal from the PMIC.

Take this gpio signal when we detect some Type-C port activity
to notify any Type-C switches tied to the Type-C port connectors.
