According to "ePAPR 1.1" spec, device should only be registered if there is no "status" property, or it has "ok" (or "okay") value (see of_device_is_available()). In case of "platform devices", of_platform_device_create_pdata() checks for "status" and ensures that disabled devices are not pupulated. But such check for MDIO buses was missing until now. Fix it.
