fip_create: add support for image unpacking

This patch adds support for image unpacking to the FIP packaging
tool. Command line option '-u,--unpack' may be used to unpack the
contents of an existing FIP file into the working directory. The
tool uses default hardcoded filenames for the unpacked images. If
the files already exist, they can be overwritten by specifying the
option '-f,--force'.

Support for Rockchip's family SoCs

This patch adds to support the RK3368 and RK3399 SoCs.

RK3368/RK3399 is one of the Rockchip family SoCs, which is an
multi-cores ARM SoCs.

This patch adds support to boot the Trusted Firmware on RK3368/RK3399
SoCs, and adds support to boot secondary CPUs, enter/exit core
power states for all CPUs in the slow/fast clusters.

This is the initial version for rockchip SoCs.(RK3368/RK3399 and next SoCs)
* Support arm gicv2 & gicv3.
* Boot up multi-cores CPU.
* Add generic CPU helper functions.
* Support suspend/resume.
* Add system_off & system_reset implementation.
* Add delay timer platform implementation.
* Support the new porting interface for the PSCI implementation.

Make:Improve version string generation portability

To get round problems encountered when building in a DOS build
environment the generation of the .o file containing build identifier
strings is modified.
The problems encounterred were:
1. DOS echo doesn't strip ' characters from the output text.
2. git is not available from CMD.EXE so the BUILD_STRING value needs
some other origin.

A BUILD_STRING value of "development build" is used for now.

MAKE_BUILD_STRINGS is used to customise build string generation in a DOS
environment. This variable is not defined in the UNIX build environment
make file helper, and so the existing build string generation behaviour
is retained in these build environments.

NOTE: This commit completes a cumulative series aimed at improving
build portability across development environments.
This enables the build to run on several new build environments,
if the relevant tools are available.
At this point the build is tested on Windows 7 Enterprise SP1,
using CMD.EXE, Cygwin and Msys (MinGW),as well as a native
Linux envionment". The Windows platform builds used
aarch64-none-elf-gcc.exe 4.9.1. CMD.EXE and Msys used Gnu
Make 3.81, cygwin used Gnu Make 4.1.

CAVEAT: The cert_create tool build is not tested on the Windows
platforms (openssl-for-windows has a GPL license).

Make:Improve directory generation portability.

Because of command differences in some build environments the "inline"
method of generating the build directory structure is not portable.
(e.g. in DOS environments the mkdir shell command fails if a directory
already exists, whereas in UNIX environments it succeeds.)

To improve portability we generate the directories needed using make,
but use the "order-only prerequisites" feature of make to prevent writes
of files into the directories generating re-builds, as suggested in the
GNU make Manual (Version 4.1 September 2014).

Build:Replace soft links with file copy.

Some build environments do not support symbolic links. This patch
removes the symlinks previously used to build fip_create and instead
copies the relevant header files.
The original motivation for using symlinks was to avoid Trusted Firmware
library headers conflicting with headers in the compiler standard
include path. Copying the header files instead has the same effect.

Like other build artefacts, the copied files are listed in .gitignore.

The distclean targets have also been updated to remove the copies.

Make:Remove calls to shell from makefiles.

As an initial stage of making Trusted Firmware build environment more
portable, we remove most uses of the $(shell ) function and replace them
with more portable make function based solutions.

Note that the setting of BUILD_STRING still uses $(shell ) since it's
not possible to reimplement this as a make function. Avoiding invocation
of this on incompatible host platforms will be implemented separately.

from plat_arm_security_setup() which is implemented by each platform.
