If you don't replace this bit with anything, who will set priv->p5_configured
for mt7530?

I intend priv->p5_configured and priv->p6_configured to be only used for
MT7531 as I have stated on the mt7530_priv description.

Ok, but given the premise of this patch set, that phylink is always available,
does it make sense for mt7531_cpu_port_config() and mt7988_cpu_port_config()
to manually call phylink methods?

All I know is that that's how the implementation of phylink's PCS support in this driver works. It expects the MAC to be set up before calling mt753x_phylink_pcs_link_up() and mt753x_phylink_mac_link_up().
