Documentation: networking: switchdev: Update port parent ID section
Update the section about switchdev drivers having to implement a
switchdev_port_attr_get() function to return
SWITCHDEV_ATTR_ID_PORT_PARENT_ID since that is no longer valid after
commit bccb30254a4a ("net: Get rid of
SWITCHDEV_ATTR_ID_PORT_PARENT_ID").
Fixes: bccb30254a4a ("net: Get rid of SWITCHDEV_ATTR_ID_PORT_PARENT_ID")
