 Change-Id: I9d42108688a9070b982ae77f77633654bc6505ed
 Reviewed-on: https://chromium-review.googlesource.com/282281

BUG=none
TEST=Tested the USB & DP status from "typec" console command.
     Observed usb_mux_set() & usb_mux_get() function are getting called
     and also the polarity of the USB-C is getting detected properly.
BRANCH=none
