usb: typec: tcpci: add tcpm_transmit_type to tcpm_pd_receive
tcpm_pd_receive adds the SOP type as a parameter, and passes it within the
pd_rx_event struct for tcpm_pd_rx_handler to use. For now, the handler
drops all SOP' messages.
Maxim based tcpci drivers are capable of SOP' communication, so process_rx
now takes the SOP type into account and passes the value to
tcpm_pd_receive.
tcpci_set_pd_rx now utilizes the cable_comm_capable flag to determine if
TCPC_RX_DETECT_SOP1 should be added to the bitfield when enabling PD
message reception.
For all other consumers of tcpm_pd_receive, default the new field to
TCPC_TX_SOP.
