plankton: Set case closed debug mux
When enable CCD, we expect DP/USB super speed MUX is switched to USB and
reset RFU polarity MUX for USB2 to recognize correct devices.
BRANCH=none
BUG=chrome-os-partner:44977
TEST=manual
Connect plankton's type-c to a PD sink, switch plankton to power source
switch DP MUX to DP, and press CCD button.
Super speed MUX should be switch to USB3 mode. And if the PD sink
supports CCD, host computer should be able to recognize CCD devices.
