TCPMv2: Request partner's revision information in src/snk startup
Adding features from the USB PD 3.1 revision of the specification
requires us to know the difference between USB PD Rev 3.0 and USB PD Rev
3.1 devices. But, the message header only has 2 bits for revision and
only provides the major revision. To determine a devices minor
revision, TCPMv2 will need to send a Get_Revision command and store the
Revision response which has major/minor revision/version information.
This CL adds support for sending Get_Revision, and receiving Revision.
BUG=b:214087135
TEST=Checked that the PE state was correctly holding the Revision
response from a USB PD Rev 3.1 partner, and also checked that the stored
RMDO value was 0 for a USB PD Rev 3.0 partner.
BRANCH=none
