css_pm_scmi: optimise cpu suspend to remove redundant scmi call ...

In css platforms where the cpu/cluster management is done by the hardware,
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.

plat/sgi: switch to using scmi ...

The Arm SGI platforms can switch to using SCMI. So enable support for
SCMI and remove portions of code that would be unused after switching
to SCMI.

sgi: disable CPU power down bit in reset handler ...

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.

Add support for romlib in the build system ...

Romlib is a new image that is stored in ROM and contains the code of
several libraries that can be shared between different images. All
the functions within in the library are accessed using a jump table
which allows to update the romlib image whithout changing the binary
compatibility. This jump table can be also stored in RAM and it can
allow to patch a romlib with potential bugs fixes..

Add atexit function to libc ...

We had exit but we didn't have atexit, and we were calling panic and
tf_printf from exit, which generated a dependency from exit to them.
Having atexit allows to set a different function pointer in every image.

Don't include mbebtls include paths in INCLUDES ...

Mbebtls include paths are controlled by the user using the variable
MBEDTLS_DIR and they are out of the TF source tree. Since these
includes have a different origin it is better to move them to a
different variable.

This change makes easier for the romlib Makefile to parse the include
paths.
