[PATCH net-next 09/30] net: dsa: mt7530: empty default case on mt7530_setup_port5()

[arinc9 . unal]

From: Arınç ÜNAL <arinc.unal@xxxxxxxxxx>

There're two code paths for setting up port 5:

mt7530_setup()
-> mt7530_setup_port5()

mt753x_phylink_mac_config()
-> mt753x_mac_config()
   -> mt7530_mac_config()
      -> mt7530_setup_port5()

On the first code path, priv->p5_intf_sel is either set to
P5_INTF_SEL_PHY_P0 or P5_INTF_SEL_PHY_P4 when mt7530_setup_port5() is run.

On the second code path, priv->p5_intf_sel is set to P5_INTF_SEL_GMAC5 when
mt7530_setup_port5() is run.

Empty the default case which will never run but is needed nonetheless to
handle all the remaining enumeration values.
