Fixed the below bugs:
1) Bug related to build flag V=1: if the flag was V=0, building with
ROMLIB would fail.
2) Due to a syntax bug in genwrappers.sh, index file entries marked as
"patch" or "reserved" were ignored.
3) Added a prepending hash to constants that genwrappers is generating.
4) Due to broken dependencies, currently the inclusion functionality is
intentionally not utilised. This is why the contents of romlib/jmptbl.i
have been copied to platform specific jmptbl.i files. As a result of the
broken dependencies, when changing the index files, e.g. patching
functions, a clean build is always required. This is a known issue that
will be fixed in the future.

This patch adds support for Versatile express FVP (Fast models).
Versatile express is a family of platforms that are based on ARM v7.
Currently this port has only been tested on Cortex A7, although it
should work with other ARM V7 cores that support LPAE, generic timers,
VFP and hardware divide. Future patches will support other
cores like Cortex A5 that dont support features like LPAE
and hardware divide. This platform is tested on and only expected to
work on single core models.

Rather than letting the Trusty makefile set the option to enable dynamic
translation tables, make platforms do it themselves.
This also allows platforms to replace the implementation of the
translation tables library as long as they use the same function
prototypes.

On ARM platforms, the BL2 memory can be overlaid by BL31/BL32. The memory
descriptors describing the list of executable images are created in BL2
R/W memory, which could be possibly corrupted later on by BL31/BL32 due
to overlay. This patch creates a reserved location in SRAM for these
descriptors and are copied over by BL2 before handing over to next BL
image.
Also this patch increases the PLAT_ARM_MAX_BL2_SIZE for juno when TBBR
is enabled.

From now on, platform_def.h must include any header with definitions that
are platform-specific (like arm_def.h) and the included headers mustn't
include back platform_def.h, and shouldn't be used by other files. Only
platform_def.h should be included in other files. This will ensure that all
needed definitions are present, rather than needing to include all the
headers in all the definitions' headers just in case.
This also prevents problems like cyclic dependencies.

A previous commit 89f2e58985 ("plat/arm: remove weak implemention of
'plat_arm_psci_override_pm_ops' function") introduced a problem with the
CSS_USE_SCMI_SDS_DRIVER configuration. In juno_pm.c the
css_scmi_override_pm_ops function was used regardless of whether the
flag was set. This patch ifdefs the function to restore the original
behaviour.

Enforce full include path for includes. Deprecate old paths.
The following folders inside include/lib have been left unchanged:
- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}
The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).
For example, this patch had to be created because two headers were
called the same way: e0ea0928d5 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a2 ("drivers: add tzc380 support").
This problem was introduced in commit 4ecca33988 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.
Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

SPM needs to map a number of regions on behalf of the secure partition.
Previously, it used to get a list of them from platform code using the
plat_get_secure_partition_mmap() API. Now it gets them from the resource
description structure.
The SPM<->SP shared buffer is mapped dynamically at EL3. This buffer is
used to pass information between SPM and SP, so it must be mapped at EL3
as well in order to be used by SPM.
Dynamic translation tables have been enabled when the Trusted Firmware
is compiled with SPM support.

With the two new APIs 'plat_arm_sgi_get_platform_id' and
'plat_arm_sgi_get_config_id' that are available now, BL31 need not
depend on hw_config device tree to identify the platform. In addition
to this, the existing hardware description in hw_config can be limited
to use by BL33 and not by the operating system.
So the hardware description from hw_config dts can be moved into
nt_fw_config dts and the use of hw_config dts can be removed.

In BL31, these functions are used to populate the 'sgi_plat_info_t'
