Subject: [PATCH v2 0/3] Add support for responding to Get_Revision request

Currently TCPM doesn't support responding to Get_Revision request
message. However, as per Message Applicability in USB PD Spec 3.1 v1.8
("6.13.2 Applicability of Data Messages") "Revision" is a Normative
(compulsory) message and needs to be supported. As part of this patchset
add support for responding to Get_Revision requests as part of
Revision_Information AMS.
