layerscape: Initial TF-A support for LS1043ardb 

This patch introduce TF-A support for NXP's ls1043a platform.
more details information of ls1043a chip and ls1043ardb board
can be found at docs/plat/ls1043a.rst.

Boot sequence on ls1043a is: bootrom loads bl1 firstly, then bl1
loads bl2, bl2 will load bl31, bl32 and bl33, bl31 will boot
bl32(tee os) and bl33(u-boot or uefi), bl33 boot Linux kernel.

Now TF-A on ls1043ardb platform has the following features in this patch:
	* Support boot from Nor flash.
	* TF-A can boot bl33 which runs in el2 of non-secure world.
	* TF-A boot OPTee OS.
	* Support PSCI

Description
===========
The QorIQ® LS1043A processor is NXP's first quad-core, 64-bit Arm®-based
processor for embedded networking. The LS1023A (two core version) and the
LS1043A (four core version) deliver greater than 10 Gbps of performance
in a flexible I/O package supporting fanless designs. This SoC is a
purpose-built solution for small-form-factor networking and industrial
applications with BOM optimizations for economic low layer PCB, lower cost
power supply and single clock design. The new 0.9V versions of the LS1043A
and LS1023A deliver addition power savings for applications such as Wireless
LAN and to Power over Ethernet systems.
LS1043ARDB Specification:
-------------------------
Memory subsystem:
* 2GByte DDR4 SDRAM (32bit bus)
* 128 Mbyte NOR flash single-chip memory
* 512 Mbyte NAND flash
* 16 Mbyte high-speed SPI flash
* SD connector to interface with the SD memory card
Ethernet:
* XFI 10G port
* QSGMII with 4x 1G ports
* Two RGMII ports
PCIe:
* PCIe2 (Lanes C) to mini-PCIe slot
* PCIe3 (Lanes D) to PCIe slot
USB 3.0: two super speed USB 3.0 type A ports
UART: supports two UARTs up to 115200 bps for console
More information are listed in `ls1043`_.
Boot Sequence
=============
Bootrom --> TF-A BL1 --> TF-A BL2 --> TF-A BL1 --> TF-A BL31
--> BL32(Tee OS) --> TF-A BL31 --> BL33(u-boot) --> Linux kernel
How to build
============
Build Procedure
---------------
- Prepare AARCH64 toolchain.
- Build u-boot and OPTee firstly, and get binary images: u-boot.bin and tee.bin
- Build TF-A for Nor boot
Build bl1:
.. code:: shell
CROSS_COMPILE=aarch64-linux-gnu- make PLAT=ls1043 bl1
Build fip:
.. code:: shell
CROSS_COMPILE=aarch64-linux-gnu- make PLAT=ls1043 fip \
BL33=u-boot.bin NEED_BL32=yes BL32=tee.bin SPD=opteed
Deploy TF-A Images
-----------------
- Deploy TF-A images on Nor flash Alt Bank.
.. code:: shell
=> tftp 82000000 bl1.bin
=> pro off all;era 64100000 +$filesize;cp.b 82000000 64100000 $filesize
=> tftp 82000000 fip.bin
=> pro off all;era 64120000 +$filesize;cp.b 82000000 64120000 $filesize
Then change to Alt bank and boot up TF-A:
.. code:: shell
=> cpld reset altbank
