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

Using the MDIO pins with Open Drain causes spec violations of the
signals. Revert the changes.
This is similar to commit 14e66e4b13221 ("Revert "arm64: dts:
imx93-tqma9352-mba93xxca: enable Open Drain for MDIO"")

Fixes: e5bc07026f94 ("arm64: add initial device tree for TQMa93xx/MBa91xxCA")
