This new C function will call sp_min_early_platform_setup2() and
sp_min_plat_arch_setup(). At this step the C environment is already
enabled, and it allows adding function like the one for early console
for which r9-r12 registers could be clobbered.

Similar to bl31_warm_entrypoint, sp_min-based platforms may need
that for special resume handling.
Therefore move it from the private header to the sp_min platform header.

All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.
The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.
The exceptions are files that are imported from other projects:
- CryptoCell driver
- dt-bindings folders
- zlib headers

Add support for a minimal secure interrupt service in sp_min for
the AArch32 implementation. Hard code that only FIQs are handled.
Introduce bolean build directive SP_MIN_WITH_SECURE_FIQ to enable
FIQ handling from SP_MIN.
Configure SCR[FIQ] and SCR[FW] from generic code for both cold and
warm boots to handle FIQ in secure state from monitor.
Since SP_MIN architecture, FIQ are always trapped when system executes
in non secure state. Hence discard relay of the secure/non-secure
state in the FIQ handler.

This patch adds a minimal AArch32 secure payload SP_MIN. It relies on PSCI
library to initialize the normal world context. It runs in Monitor mode
and uses the runtime service framework to handle SMCs. It is added as
a BL32 component in the Trusted Firmware source tree.
