[PATCH v2 2/2] arm64: dt: imx93-tqma9352-mba93xxla: enable Open Drain for MDIO

From: Markus Niebel <Markus.Niebel at ew.tq-group.com>

The board has a pull-up resistor for MDIO pin per PHY design guide.
When MDIO is idle, it needs to be high and open drain is better
to be used here for power saving.
