net: dsa: mt7530: empty default case on mt7530_setup_port5()
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.
