usb: typec: tcpm: Add new AMS for Get_Revision response
This commit adds a new AMS for responding to a "Get_Revision" request.
Revision message consists of the following fields:
+----------------------------------------------------+
| Header | RMDO |
| No. of data objects = 1 | |
+----------------------------------------------------+
While RMDO consists of:
* B31..28 Revision Major
* B27..24 Revision Minor
* B23..20 Version Major
* B19..16 Version Minor
* B15..0 Reserved, shall be set to zero.
As per the PD spec ("8.3.3.16.2.1 PR_Give_Revision State"), a request is
only expected when an explicit contract is established and the port is
in ready state. This AMS is only supported for PD >= 3.0.
