Subject[PATCH v6 1/7] platform/chrome: Add Type-C mux set command definitions
Date
Copy EC header definitions for the USB Type-C Mux control command from
the EC code base. Also pull in "TBT_UFP_REPLY" definitions, since that
is the prior entry in the enum.

These headers are already present in the EC code base. [1]
