This adds device trees for the ADI Engineering Coyote and the
Intel IXDPG425 reference design. The ethernet set-up on the
IXDPG425 is a bit dubious because I think it uses a DSA
switch chip, but this is a good as it gets right now.
The Coyote boardfile claims an IDE port exist at 0xFFFE1000
but the implementation does not use this. If you have the
board and can/want to test, please contact me.

Zoltan: looping you on this patch since you have the Pronghorn
which I think is the sequel to the Coyote.
