dt-bindings: Add cros-ec Type C port driver
Some Chrome OS devices with Embedded Controllers (EC) can read and
modify Type C port state.
Add an entry in the DT Bindings documentation that lists out the logical
device and describes the relevant port information, to be used by the
corresponding driver.
