net: designware: eqos: fix MDIO regression for STM32MP1 boards
The STM32MP1 boards call their mdio subnode mdio0, which is now skipped
since ed8c7bdf8592 ("net: designware: eqos: set mdio bus device node").
Fix networking for them by only falling back to the mdio node name when a
child node with the correct compatible could not be found.
Fixes: ed8c7bdf8592 ("net: designware: eqos: set mdio bus device node")
