mediatek: filogic: mt-stuart: move AQR113C reset to MDIO bus level

Each board wires one reset line that resets the AQR113C PHYs as a
group: GPIO 71 on SDG-8733/SDG-8734 and GPIO 62 on SDG-8733A.
Describe that line as the MDIO bus reset with the same assert and
deassert times.

Drop the per-PHY reset-gpios. On SDG-8733 the second AQR113C
claimed GPIO 62, which is not connected on that board.
