[PATCH net 4/4] net: mscc: Fix OF_MDIO config check

[Dan Murphy <dmurphy@ti.com>]

When CONFIG_OF_MDIO is set to be a module the code block is not
compiled. Use the IS_ENABLED macro that checks for both built in as
well as module.

Fixes: 4f58e6dceb0e4 ("net: phy: Cleanup the Edge-Rate feature in Microsemi PHYs.")
