serial: core: restore of_node information in sysfs
commit d36f0e9a0002f04f4d6dd9be908d58fe5bd3a279 upstream.
Since in v6.8-rc1, the of_node symlink under tty devices is
missing. This breaks any udev rules relying on this information.
Link the of_node information in the serial controller device with the
parent defined in the device tree. This will also apply to the serial
device which takes the serial controller as a parent device.
Fixes: b286f4e87e32 ("serial: core: Move tty and serdev to be children of serial core port device")
