Guenter Roeck df3f5efe10 hw/net/imx_fec: Support two Ethernet interfaces connected to single MDIO bus 
The SOC on i.MX6UL and i.MX7 has 2 Ethernet interfaces. The PHY on each may
be connected to separate MDIO busses, or both may be connected on the same
MDIO bus using different PHY addresses. Commit 461c51ad42 ("Add a phy-num
property to the i.MX FEC emulator") added support for specifying PHY
addresses, but it did not provide support for linking the second PHY on
a given MDIO bus to the other Ethernet interface.

To be able to support two PHY instances on a single MDIO bus, two properties
are needed: First, there needs to be a flag indicating if the MDIO bus on
a given Ethernet interface is connected. If not, attempts to read from this
bus must always return 0xffff. Implement this property as phy-connected.
Second, if the MDIO bus on an interface is active, it needs a link to the
consumer interface to be able to provide PHY access for it. Implement this
property as phy-consumer.
