Support shared Mbed TLS heap for FVP

This patch introduces the shared Mbed TLS heap optimisation for Arm
platforms. The objective is the Mbed TLS heap to be shared between BL1
and BL2 so as to not allocate the heap memory twice. To achieve that,
the patch introduces all the necessary helpers for implementing this
optimisation. It also applies it for FVP.

Prepare Mbed TLS drivers for shared heap

The Mbed TLS drivers, in order to work, need a heap for internal usage.
This heap, instead of being directly referenced by the drivers, now it
is being accessed indirectly through a pointer. Also, the heap, instead
of being part of the drivers, now it is being received through the
plat_get_mbedtls_heap() function. This function requests a heap from the
current BL image which utilises the Mbed TLS drivers.

Those changes create the opportunity for the Mbed TLS heap to be shared
among different images, thus saving memory. A default heap
implementation is provided but it can be overridden by a platform
specific, optimised implemenetation.

backtrace: Introduce backtrace function

This function diplays the backtrace, the current EL and security state
to allow a post-processing tool to choose the right binary to interpret
the dump.

The output can be fed to GNU addr2line to resolve function names given
an ELF binary compiled with debug information. The "-i" flag is
recommended to improve display in case of inlined functions. The *.dump
files generated during the build process can also be used.

The function works in AArch64 and AArch32. In AArch32 it only works in
A32 mode (without T32 interworking), which is enforced in the Makefile.

Sample output of a backtrace at EL3:

BACKTRACE: START: function_name
0: EL3: 0x798
1: EL3: 0x538
2: EL3: 0x550
3: EL3: 0x55c
4: EL3: 0x568
5: EL3: 0x5a8
6: EL3: 0xf4
BACKTRACE: END: function_name

In order to enable it the new option ENABLE_BACKTRACE must be set to 1.
This option is set to 1 by default only in AArch64 debug builds. As
usual, it can be overridden by the platform makefile and in the build
command line.

Allow manually setting the AArch32 instruction set

At the moment the AArch32 instruction set isn't specified in the command
line, which means that the compiler is free to choose the one it sees
fit. This decision may change between compiler versions, so it is better
to specify it manually.

The build option AARCH32_INSTRUCTION_SET has been introduced for this
reason. This option can be set to T32 or A32 to pass the correct flags
to the compiler.

The current behaviour is to default to T32 due to it's smaller size.

context_mgmt: Fix HANDLE_EA_EL3_FIRST implementation

This patch fixes a bug in the context management code that causes it to
ignore the HANDLE_EA_EL3_FIRST compile-time option and instead always
configure SCR_EL3 to force all external aborts to trap into EL3. The
code used #ifdef to read compile-time option declared with add_define in
the Makefile... however, those options are always defined, they're just
defined to either 0 or 1, so #if is the correct syntax to check for
them. Also update the documentation to match.

This bug has existed since the Nov 2017 commit 76454abf4 (AArch64:
Introduce External Abort handling), which changed the
HANDLE_EA_EL3_FIRST option to use add_define.

AArch64: Enable MPAM for lower ELs

Memory Partitioning And Monitoring is an Armv8.4 feature that enables
various memory system components and resources to define partitions.
Software running at various ELs can then assign themselves to the
desired partition to control their performance aspects.

With this patch, when ENABLE_MPAM_FOR_LOWER_ELS is set to 1, EL3 allows
lower ELs to access their own MPAM registers without trapping to EL3.
This patch however doesn't make use of partitioning in EL3; platform
initialisation code should configure and use partitions in EL3 if
required.
