imx: kontron-sl-mx6ul: Enable CONFIG_DM_MDIO to fix boot abort
The following failure occurs right before switching to the kernel:

Resetting CPU ...
This is due to the fact that the board uses a shared MDIO bus for
both ethernet controllers, but FEC_MXC_SHARE_MDIO is not enabled.
This results in a double free in fecmxc_remove(). To fix this
enable CONFIG_DM_MDIO so the shared MDIO is correctly detected
from the devicetree.
