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

Juno: Increase bl2 max size to fix build when SPD=opteed

Building TBBR(SPD=opteed) and non-TBBR TF-A images is breaking for
Juno for different configurations listed below:

* Overflow error of 4096 bytes for rsa algorithm.
* Overflow error of 8192 bytes for ecdsa algorithm.
* Overflow error of 4096 bytes for rsa+ecdsa algorithm.
* Overflow error of 4096 bytes for non-TBBR case.

So this patch increments macro PLAT_ARM_MAX_BL2_SIZE for all the above
cases accordingly.

FVP: Fix function for translating MPIDR to linear index

The current AArch32 version of plat_arm_calc_core_pos uses an incorrect
algorithm to calculate the linear position of a core / PE from its
MPIDR.

This patch corrects the algorithm to:

(ClusterId * FVP_MAX_CPUS_PER_CLUSTER) * FVP_MAX_PE_PER_CPU
+ (CPUId * FVP_MAX_PE_PER_CPU)
+ ThreadId

which supports cores where there are more than 1 PE per CPU.

NOTE: the AArch64 version was fixed in 39b21d1

qemu: don't use C functions for the crash console callbacks

Use the console_pl011_core_* functions directly in the crash console
callbacks.

This bypasses the MULTI_CONSOLE_API for the crash console (UART1), but
allows using the crash console before the C runtime has been initialized
(eg to call ASM_ASSERT). This retains backwards compatibility with respect
to functionality when the old API is used.

Use the MULTI_CONSOLE_API to register UART0 as the boot and runtime
console.

Clean usage of void pointers to access symbols

Void pointers have been used to access linker symbols, by declaring an
extern pointer, then taking the address of it. This limits symbols
values to aligned pointer values. To remove this restriction an
IMPORT_SYM macro has been introduced, which declares it as a char
pointer and casts it to the required type.

rpi3: Use new console APIs

The crash console doesn't use this API, it uses internally the core

rpi3: Use new console APIs

Switch to the new console APIs enabled by setting MULTI_CONSOLE_API=1.

The crash console doesn't use this API, it uses internally the core
functions of the 16550 console.

`bl31_plat_runtime_setup` is no longer needed. When this platform port
was introduced, that function used to disable the console. It was needed
to override that behaviour. The new behaviour is to switch to the
runtime console. The console is registered for all scopes (boot, crash
and runtime) in `rpi3_console_init` so it is not needed to override the
default behaviour anymore.

Update documentation.
