A recent commit 030567e6

 added U()/ULL()
macro to TF constants. This has caused some signed-unsigned comparison
warnings / errors in the TF static analysis.

This patch addresses these issues by migrating impacted variables from
signed ints to unsigned ints and vice verse where applicable.

The new PSCI topology framework and PSCI extended State framework introduces
a breaking change in the platform port APIs. To ease the migration of the
platform ports to the new porting interface, a compatibility layer is
introduced which essentially defines the new platform API in terms of the
old API. The old PSCI helpers to retrieve the power-state, its associated
fields and the highest coordinated physical OFF affinity level of a core
are also implemented for compatibility. This allows the existing
platform ports to work with the new PSCI framework without significant
rework. This layer will be enabled by default once the switch to the new
PSCI framework is done and is controlled by the build flag ENABLE_PLAT_COMPAT.
