This patch adds support for having a "fixed-link" to some other MAC (like some embedded switch-device). For this purpose we introduce a new phy-driver, called "Fixed PHY". Fixed PHY works only with CONFIG_DM_ETH enabled, since the fixed-link is described with a subnode below ethernet interface. Most ethernet drivers (unfortunately not all are following same scheme for searching/attaching phys) are calling "phy_connect(...)" for getting a phy-device. At this point we link in, we search here for a subnode called "fixed- link", once found we start phy_device_create(...) with the special phy- id PHY_FIXED_ID (0xa5a55a5a). During init the "Fixed PHY" driver has registered with this id and now gets probed, during probe we get all the details about fixed-link out of dts, later on the phy reports this values.
