RD Babiera fb7ff25ae4 usb: typec: tcpm: add discover identity support for SOP' 
Add data message handling and Discover Identity SVDM over SOP'

This patch contains the following changes:
    1. pd_vdo
Add VDO indices for active and passive cables, documentation to reflect
expected number of objects depending on PD Revision, and macro to indicate
port parter is data host capable.
    2. tcpm
Add typec_cable and typec_plug to tcpm_port to maintain cable and plug
information. tcpm_port also adds send_discover_prime to indicate that
Discover Identity should be sent out of the ready state.

tcpm_queue_vdm and tcpm_send_vdm now take the SOP* type when transmitting
messages. tcpm_handle_vdm_request and tcpm_pd_svdm also use the SOP* type.
tcpm_pd_svdm handles Discover Identity messages for SOP and SOP'. In the
SOP case, the port uses tcpm_attempt_vconn_swap_discovery to determine if
a Vconn swap is needed for cable communication. Otherwise, the port will
send Discover Identity on SOP' if it can, or default to Discover SVIDs.

svdm_consume_identity_sop_prime consumes the result of Discover Identity
on SOP'. It fills out cable identity and description, and it registers
the cable. The SOP' plug is registered as well.

The VDM state machine is adjusted to construct messages based on the SOP*
type. If a transmission error occurs after the max number of retries for
Discover Identity over SOP', then the port will send Discover SVIDs over
SOP.
