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
