feat(fvp): allow SIMD context to be put in TZC DRAM

This patch demonstrates the capability of SEPARATE_SIMD_SECTION build
flag through which the memory intensive SIMD context data structures
are allocated in a separate section withtin the TZC DRAM space.

plat/arm: Sanitise includes

Use full include paths like it is done for common includes.

This cleanup was started in commit d40e0e08283a ("Sanitise includes
across codebase"), but it only cleaned common files and drivers. This
patch does the same to Arm platforms.

Standardise header guards across codebase

All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.

The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.

The exceptions are files that are imported from other projects:

- CryptoCell driver
- dt-bindings folders
- zlib headers

Reclaim BL31 initialization code memory for runtime data

FVP: Reclaim init code for the stack

Map the initialization code for BL31 to overlap with the memory
required for the secondary cores stack. Once BL31 has been
initialized the memory can be remapped to RW data so that it can
be used for secondary cores stacks. By moving code from .text to
.text.init the size of the BL31 image is decreased by a page.

Split arm_common.ld.S into two linker scripts, one for tzc_dram
(arm_tzc_dram.ld.S) and one for reclaiming initialization code
(arm_reclaim_init.ld.S) so that platforms can chose which memory
regions they wish to include.

ARM platforms: Add support for EL3 TZC memory region

Some recent enhancements to EL3 runtime firmware like support for
save and restoring GICv3 register context during system_suspend
necessitates additional data memory for the firmware. This patch
introduces support for creating a TZC secured DDR carveout for use
by ARM reference platforms. A new linker section `el3_tzc_dram` is
created using platform supplied linker script and data marked with
the attribute `arm_el3_tzc_dram` will be placed in this section.
The FVP makefile now defines the `PLAT_EXTRA_LD_SCRIPT` variable to
allow inclusion of the platform linker script by the top level BL31
linker script.
