Fix duplicate PD RX event when using combined TCPM/TCPC. Problem is that PD_EVENT_RX is already set in the phy layer in pd_rx_event when CC edges are detected. Therefore, we shouldn't set it again when the TCPC detects that receiving has started. BUG=none BRANCH=none TEST=test on samus. without this change we occasionally get a PD error and hard reset under certain timing circumstances due to the repeated event. with this change, those errors go away.
