[RFC PATCHv1 5/5] arm: kirkwood: convert db-88f6281 to the Device Tree

This commit converts the db-88f6281 board to the Device Tree.
Note: this commit is not entirely correct. The db-88f6281 code was in
fact handling both the case of a board having the 6281 (one PCIe
interface) and the 6282 (two PCIe interfaces). For now, we make the
assumption that we have two PCIe interfaces (because that's the board
I have in my hands). We'll probably have to create two separate Device
Trees to distinguish between those two boards.
