TCPMv2: Support mode entry for SOP' and SOP''
Add a transmit type parameter to functions involved in mode entry; also
add such a parameter to various functions calling those functions. For
DisplayPort-specific definitions or calls, specify SOP; we do not
currently support DisplayPort mode for cable plugs. For TCPMv1-specific
code, specify SOP. TCPMv1 generally assumes that the discovery/mode
structures are 1-dimensional, as they were previously, and changing that
is outside the scope of this CL.
