Yutang Jiang c6c731fe31 layerscape: add 64b/32b target for ls1043ardb device 
Add support for NXP layerscape ls1043ardb 64b/32b Dev board.

LS1043a is an SoC with 4x64-bit up to 1.6 GHz ARMv8 A53 cores.
ls1043ardb support features as: 2GB DDR4, 128MB NOR/512MB NAND, USB3.0, eSDHC,
I2C, GPIO, PCIe/Mini-PCIe, 6x1G/1x10G network port, etc.

64b/32b ls1043ardb target is using 4.4 kernel, and rcw/u-boot/fman images from
NXP QorIQ SDK release.

All of 4.4 kernel patches porting from SDK release or upstream.

QorIQ SDK ISOs can be downloaded from this location:
