arm_bl2_handle_post_image_load to prevent two weak definitions
of the same function

TI-SCI message protocol provides support for controlling of various
physical cores available in the SoC. In order to control which host is
capable of controlling a physical processor core, there is a processor
access control list that needs to be populated as part of the board
configuration data.
Introduce support for the set of TI-SCI message protocol APIs that
provide us with this capability of controlling physical cores.

Since system controller now has control over SoC power management, core
operation such as reset need to be explicitly requested to reboot the SoC.

TI-SCI message protocol provides support for management of various
hardware entities within the SoC.
In general, we expect to function at a device level of abstraction,
however, for proper operation of hardware blocks, many clocks directly
supplying the hardware block needs to be queried or configured.
Introduce support for the set of TI-SCI message protocol support that
provide us with this capability.

Texas Instrument's System Control Interface (TI-SCI) Message Protocol
is used in Texas Instrument's System on Chip (SoC) such as those
in K3 family AM654x SoCs to communicate between various compute
processors with a central system controller entity.

The codebase was using non-standard headers. It is needed to replace
them by the correct ones so that we can use the new libc headers.

All the arm platforms were including the files related to
mem-protect. This configuration generates some problems
with new platforms that don't support such functionality,
and for that reason this patch moves these files to the
platform specific makefiles.

The translation library is useful elsewhere. Even though this repository
doesn't exercise the EL2 support of the library, it is better to have it
here as well to make it easier to maintain.
enable_mmu_secure() and enable_mmu_direct() have been deprecated. The
functions are still present, but they are behind ERROR_DEPRECATED and
they call the new functions enable_mmu_svc_mon() and
enable_mmu_direct_svc_mon().

Functions provided by stdio.h such as printf and sprintf are available
in the codebase, but they add a lot of code to the final image if they
are used:
- AArch64: ~4KB
- AArch32: ~2KB in T32, ~3KB in A32
tf_printf and tf_snprintf are a lot more simple, but it is preferable
to use them when possible because they are also used in common code.

software does need to issue certain scmi requests.
This patch wraps those scmi calls around the HW_ASSISTED_COHERENCY
build option to remove them on platforms that have this hardware support.

On SGI platforms, the 'CORE_PWRDN_EN' bit of 'CPUPWRCTLR_EL1'
register requires an explicit write to clear it for hotplug and
idle to function correctly. The reset value of this bit is zero
but it still requires this explicit clear to zero. This indicates
that this could be a model related issue but for now this issue can
be fixed be clearing the CORE_PWRDN_EN in the platform specific
reset handler function.
