drivers: ethernet: stm32: Use MDIO API only if enabled by DTS

Not all STM32 series support Zephyr MDIO API yet, while the API is enabled by default. To preserve compatibility, put MDIO API related code under the condition of "st,stm32-mdio" compatible enablement. Signed-off-by: Erwan Gouriou <[email protected]> (cherry picked from commit 2d81351)
