arm64: dts: meson-sm1-odroid: use correct enable-gpio pin for tf-io regulator

[ Upstream commit 323ca765bfe9d637fa774373baec0bc41e51fcfa ]

The interrupt pin of the external ethernet phy is used, instead of the
enable-gpio pin of the tf-io regulator. The GPIOE_2 pin is located in
the gpio_ao bank.

This causes phy interrupt problems at system startup.
