net: dsa: yt921x: Fix external port detection
The YT921x switch has two MAC ports: 8 and 9. Currently, the driver
only allows port 8 as an external port, while port 9 is not working:
yt921x mdio-bus:1d: Wrong mode 23 on port 9
yt921x mdio-bus:1d: Failed to config port 9: -22
Update the external port detection logic to enable the external PHY
connected to port 9.
Cc: stable+noautosel@kernel.org # never worked
