Subject: [PATCH v2 2/2] platform/chrome: cros_ec_typec: Set parent of partner PD object

In order to tell what Type-C device a PD object belongs to, its parent
needs to be set. Use the Type-C partner USB PD registration wrapper
to set the parent appropriately for PD objects which are created for
connected Type-C partners.
