The IXDP425, IXCDP1100, KIXRP435 and IXDP465 are similar Intel reference
designs for IXP42x, IXP43x and IXP4[56]x.
This adds device trees for these so the board files can be migrated.

Vladimir: I only have a stub for the NAND, I don't find any
references to this NAND chip in the Intel user guides, so if you
want me to fix this up better I need more information on this.
