usb: typec: tcpci: add cable_comm_capable attribute

Browse source

Add cable_comm_capable to tcpci_data for tcpci drivers to indicate that
the port tcpc is capable of communicating to cables over SOP. A
corresponding tcpci callback tcpci_cable_comm_capable returns this value.
The tcpm will primarily use this in later patches to determine if the port
can transmit and receive SOP' messages.

Maxim based tcpci drivers are capable of SOP' communication, so the
cable_comm_capable flag is set to true.
