port has a retimer (instead of assuming that all ports have retimers).
BUG=b:263964979
TEST=Verified on guybrush; SSDT shows retimer-switch on port1 when
device tree is updated accordingly.

On some systems, the Chrome EC controls both the USB Type-C mux as well
as the retimer. Introduce a boolean property "mode-switch" to denote
switches which act as a mode-switch.
