TCPMV2: Gate Alert USB PD 3.1 fields on partner revision
Extended alert events were added in USB PD 3.1, but will currently be
sent to all USB PD 3.0 partners. This CL clears ADO fields added in USB
PD 3.1 before sending alerts to USB PD 3.0 partners. If clearing the
extended alert bits sets the ADO to 0, it will not send the alert.
BUG=b:237336333
BRANCH=None
TEST=Checked alert was not being sent to USB PD 3.0 parnter on power
state change, and passing all unit tests (make runhosttests).
