ARM: dts: ixp4xx: Add device trees for Coyote and IXDPG425
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.
