arm: dts: dra72: Use gpio hog only for baseboard ethernet

On J6eco EVM, the ethernet is muxed with the vin2a interface.
For using vin2a, ethernet slave0 is rerouted to use the PHY1.
This is done by hogging a GPIO to output-low.

For vision use cases, we need to set the GPIO from driver.
Therefore, hogging is not correct solution. Also, gpio-hog does not
respect the status="disabled" property.

So keep the gpio hog node in baseboard dts but delete from the vision dts.
This will enable ethernet on baseboard and would allow setting thr GPIO
for vision use cases.
