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:
http://www.nxp.com/products/software-and-tools/run-time-software/linux-sdk/linux-sdk-for-qoriq-processors:SDKLINUX

+ state
+
+To support loading a 32-bit OS, the execution state will change from
+AArch64 to AArch32 when jumping to kernel.
+
+The architecture information will be got through checking FIT
+image, then U-Boot will load 32-bit OS or 64-bit OS automatically.

+Subject: [PATCH 02/93] armv8: SMP support for loading 32-bit OS
+
+Spin-table method is used for secondary cores to load 32-bit OS. The
+architecture information will be got through checking FIT image and
+saved in the os_arch element of spin-table, then the secondary cores
+will check os_arch and jump to 32-bit OS or 64-bit OS automatically.

+Subject: [PATCH 03/93] armv8: aarch32: Disable CONFIG_FSL_LS_PPA for loading
+ 32-bit OS
+
+The current U-Boot doesn't support loading 32-bit OS with PPA, so
+disable CONFIG_FSL_LS_PPA so far.

+Subject: [PATCH 04/93] armv8: Support loading 32-bit OS which is not in the
+ form of FIT
+
+As only FIT image is supported now, this patch is to support loading
+32-bit uImage, dtb and rootfs separately.
