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.

TI-SCI message protocol provides support for management of various

In general, we expect to function at a device level of abstraction,

supplying the hardware block needs to be queried or configured.

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.

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.
