arm/km: enable FDT for km_kirwkood
This consists of:
a) Defining the addresses, enabling fdtsupport [arm]
b) Defining "cramfsloadfdt" [arm,powerpc => common]
c) Adding the FDT address to bootm [arm,powerpc => common]
d) Defining "tftpfdt" in ramfs-,develop- [arm,powerpc >= common]
This should work with 3.10 kernels, whether loaded through TFTP
(with rootfs either through NFS or TFTP-ramfs) or from the NAND.
The machid was left unchanged, this should keep compatibility with both
older and newer kernels.
