Drop this device_type.

And this one.

This device_type/compatible/model stuff is also crap, although I
suspect it needs to be fixed in the driver, as gianfar (finally) was.

And drop this device_type.

And this one.

This node needs a "compatible" too.

This should probably be clock-frequency, not bus-frequency.  After
all, it's a bus node, what other sort of frequency would it be.

And this device_type needs to go, too.

And this one.

And this one.

And this one.

These phy nodes have basically no information in them.  PHY nodes are
optional - only include them if they actually have something useful to
say (which would mean at least a compatible property).

Drop this device_type, too.

And this node, too, needs a "compatible" property.  Oh, and the node
name should be "interrupt-controller at 80" by the generic names
convention.
