Subject: [PATCH 15/15] net: dsa: mt7530: explain exposing MDIO bus of MT7531AE

Unlike MT7531BE, the GPIO 6-12 pins are not used for RGMII on MT7531AE.
Therefore, the GPIO 11-12 pins are set to function as MDC and MDIO to
expose the MDIO bus of the switch. Replace the comment with a better
explanation.
