CONFIG_MDIO_BUS was previously a hidden symbol that was selected by
CONFIG_MDIO_DEVICE, however since kernel 6.16 this changed.
CONFIG_MDIO_DEVICE was dropped and now CONFIG_MDIO_BUS is visible and must
be directly selected[1].
So, enable CONFIG_MDIO_BUS directly as otherwise building mdio-tools can
fail with:
ERROR: modpost: "mdio_find_bus" [mdio-netlink.ko] undefined!
ERROR: modpost: "__mdiobus_write" [mdio-netlink.ko] undefined!
ERROR: modpost: "__mdiobus_read" [mdio-netlink.ko] undefined!
