[PATCH 3/7] platform/chrome: cros_ec_typec: Clear partner identity on device removal

The partner identity struct isn't reset when a partner is removed,
meaning a subsequent partner can inherit an old partner's identity VDOs
before discovery is complete. So, clear that struct when a partner
removal is detected.
