From: Alexander Sverdlin <redacted> of_mdio: Honour "status=disabled" property of device Currently of_mdiobus_register() function registers all PHY devices, independetly from their status property in device tree. 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.
