Add support for parsing "pd-revision" DT property in TCPM and store PD revision and version supported by the Type-C connnector. It should be noted that the PD revision is the maximum possible revision supported by the port. This is different from the 2 bit revision set in PD msg headers. The purpose of the 2 bit revision value is to negotiate between Rev 2.X & 3.X spec rev as part of contract negotiation, while this is used for Get_Revision AMS after a contract is in place.
