of/mdio: Add support function for Ethernet fixed-link property
Fixed-link support is broken for the ucc_eth, gianfar, and fs_enet
device drivers. The "OF MDIO rework" patches removed most of the
support. Instead of re-adding fixed-link stuff to the drivers, this
patch adds a support function for parsing the fixed-link property
and obtaining a dummy phy to match.
Note: the dummy phy handling in arch/powerpc is a bit of a hack and
needs to be reworked. This function is being added now to solve the
regression in the Ethernet drivers, but it should be considered a
temporary measure until the fixed link handling can be reworked.
