To support reporting link state of PHYs attached to built-in switch,
add a device tree knob which allows to force 1000Mbps/FD mode,
which is the link mode between eth1 MAC and the on-chip switch, even if
no "fixed-link" node is present. Re-use the "builtin-switch" name
already used in respective MDIO nodes.
This way, a phy-handle property can be added to eth1 node, and devices,
which have a single port attached through the built-in switch,
can report proper link state of that to userspace.
To perform that, one needs to delete the 'fixed-link' node and map the
correct swphy node to 'phy-handle' property. One of those is still
required to be present in the eth1 node.
