layerscape: add Traverse LS1043-S support

The Traverse LS1043-S board is a router board based on
NXP/Freescale's LS1043 SoC, with 4x1GBase-T, 1 SFP and 1 SFP+,
as well as miniPCIe and M.2 LTE.

Unlike the Layerscape reference boards, the LS1043-S board has
NAND flash and uses the mainline U-Boot.

This patch implements support for the LS1043-S board, as well as
the earlier LS1043-V board. It is our intention that all boards
in this family (LS1043-S and later, Five64) will boot the same binary.

Not included in this patchset are the hwmon drivers not in the kernel
(emc1704,pac1934) or the bootloader.
