TCPMv1: Add support for Thunderbolt active cables
For entering into Thunderbolt-Compatible mode with active
cable, the port sends Enter mode command for SOP', SOP''
(if the cable has a SOP'' controller) and SOP respectively.
If the port doesn't receive GoodCRC from Enter Mode SOP'',
the port resets the cable characteristic and exits the
Thunderbolt-Compatible mode discovery.
This CL enables SOP'' communication with the cable plug
and adds support to enter into Thunderbolt-compatible mode
with active cables.
BUG=b:140643923
BRANCH=None
TEST=Able to enter into Thunderbolt-Compatible mode for
active cables.
