As DRP port autonomously toggles the Rp/Rd need a start value to
begin with, so add one parameter for it in tcpm_start_drp_toggling.
It does have a starting value. The patch changes the starting value to TYPEC_CC_RD
(from currently one of the RP states) when entering the SNK_UNATTACHED state.
Please provide a matching description.
