This patch defines a SMCC context to save and restore
registers during a SMC call. It also adds appropriate helpers
to save and restore from this context for use by AArch32
secure payload and BL stages.

AArch32: Add API to invoke runtime service handler

This patch adds an API in runtime service framework to
invoke the registered handler corresponding to the SMC function
identifier. This is helpful for AArch32 because the number of
arguments required by the handler is more than registers
available as per AArch32 program calling conventions and
requires the use of stack. Hence this new API will do the
necessary argument setup and invoke the appropriate
handler. Although this API is primarily intended for AArch32,
it can be used for AArch64 as well.

AArch32: Add tf_printf support

The tf_printf library uses 64 bit division to print numbers
in appropriate formats but AArch32 mode cannot do 64 bit division
natively. Hence this patch adds additional number printing routines
to handle AArch32 mode in tf_printf library. The decimal format
printing capability is limited to 32 bit integers whereas 64 bits
are supported in hexadecimal format. The library assumes that
secure world is running in Little-Endian mode to do bit
manipulations on 64 bit. Suitable assertions are present to
enforce this assumption.

AArch32: Add assembly helpers

This patch adds various assembly helpers for AArch32 like :

* cache management : Functions to flush, invalidate and clean
cache by MVA. Also helpers to do cache operations by set-way
are also added.

* stack management: Macros to declare stack and get the current
stack corresponding to current CPU.

* Misc: Macros to access co processor registers in AArch32,
macros to define functions in assembly, assert macros, generic
`do_panic()` implementation and function to zero block of memory.

AArch32: Add essential Arch helpers

This patch adds the essential AArch32 architecture helpers
arch.h and arch_helpers.h and modifies `_types.h` to add AArch32
support.

A new build option `ARCH` is defined in the top level makefile to
enable the component makefiles to choose the right files based on the
Architecture it is being build for. Depending on this flag, either
`AARCH32` or `AARCH64` flag is defined by the Makefile. The default
value of `ARCH` flag is `aarch64`. The AArch32 build support will be
added in a later patch.

Replace fip_create with fiptool

fiptool provides a more consistent and intuitive interface compared to
the fip_create program. It serves as a better base to build on more
features in the future.

fiptool supports various subcommands. Below are the currently
supported subcommands:

1) info - List the images contained in a FIP file.
2) create - Create a new FIP file with the given images.
3) update - Update an existing FIP with the given images.
4) unpack - Extract a selected set or all the images from a FIP file.
5) remove - Remove images from a FIP file. This is a new command that
was not present in fip_create.

To create a new FIP file, replace "fip_create" with "fiptool create".

To update a FIP file, replace "fip_create" with "fiptool update".

To dump the contents of a FIP file, replace "fip_create --dump" with
"fiptool info".

A compatibility script that emulates the basic functionality of
fip_create is provided. Existing scripts might or might not work with
the compatibility script. Users are strongly encouraged to migrate to
fiptool.

This patch fixes the offset of GICD_IROUTER register defined in gicv3.h.
Although the GICv3 documention mentions that the offset for this register
is 0x6100-0x7FD8, the offset calculation for an interrupt id `n` is :

0x6000 + 8n, where n >= 32

This requires the offset for GICD_IROUTER to be defined as 0x6000.
