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SWITCHDEV_ATTR_ID_PORT_PARENT_ID since that is no longer valid after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 bccb30254a ("net: Get rid of
SWITCHDEV_ATTR_ID_PORT_PARENT_ID").

Fixes: bccb30254a ("net: Get rid of SWITCHDEV_ATTR_ID_PORT_PARENT_ID")

Switch ID
^^^^^^^^^
The switchdev driver must implement the switchdev op switchdev_port_attr_get
for SWITCHDEV_ATTR_ID_PORT_PARENT_ID for each port netdev, returning the same
physical ID for each port of a switch. The ID must be unique between switches
on the same system. The ID does not need to be unique between switches on
different systems.
The switchdev driver must implement the net_device operation
ndo_get_port_parent_id for each port netdev, returning the same physical ID for
each port of a switch. The ID must be unique between switches on the same
system. The ID does not need to be unique between switches on different
systems.
The switch ID is used to locate ports on a switch and to know if aggregated
ports belong to the same switch.
