Vincent Palatin 9e07dfb6cb pd: export the data role to the AP 
For dual-role USB ports (host/device), let the AP know whether we are
currently DFP (USB host) or UFP (USB device) by exporting the data role
in addition to the power role in the EC_CMD_USB_PD_CONTROL response.

plug various accessories on the port and see properly "SRC DFP" for the
USB key, "SNK DFP" for the power supply and "SNK UFP" for a regular
C-to-A charging cable.
