usb: typec: ucsi: Fix the partner PD revision
The Partner PD Revision field in GET_CONNECTOR_CAPABILITY
data structure was introduced in UCSI v2.1. In
ucsi_check_connector_capability() the version was assumed to
be 2.0, and in ucsi_register_partner() the field is accessed
completely unconditionally.
Fixing the version in ucsi_check_connector_capability(), and
replacing the unconditional pd_revision assignment with a
direct call to ucsi_check_connector_capability() in
ucsi_register_port(). After this the revision is also
checked only if there is a PD contract.
