This patch removes re-definition of the following FVP build
options from plat\arm\board\fvp\fvp_def.h:
 'FVP_CLUSTER_COUNT'
 'FVP_MAX_CPUS_PER_CLUSTER'
 'FVP_MAX_PE_PER_CPU'
which are set in platform.mk.

This fixes a potential problem when a build option set in
platform.mk file can be re-defined in fvp_def.h header file
used by other build component with a different makefile which
does not set this option.
Ref. GENFW-3505.

In further patches, we aim to enable -Wredundant-decls by default.
This rearragement of helper macros is necessary to make Coverity
tool happy as well as making sure there are no redundant function
declarations for PMF related declarations.

Also, PMF related macros were added to provide appropriate function
declarations for helper APIs which capture PSCI statistics.

The MCE driver's helper functions were using postive values as error
codes.

This patch updates the functions to return negative values as error
codes instead. Some functions are updated to use the right error code.

The reclaim init code functionality relies on forward reference in the
linker script. The LLVM linker does not process it correctly.

The SCU connects one to four Cortex-A5/Cortex-A9 processors
to the memory system through the AXI interfaces.

The SCU functions are to:
- maintain data cache coherency between the Cortex-A5/Cortex-A9
  processors
- initiate L2 AXI memory accesses
- arbitrate between Cortex-A5/Cortex-A9 processors requesting
  L2 accesses
- manage ACP accesses.

Snoop Control Unit will enable to snoop on other CPUs caches.
This is very important when it comes to synchronizing data between
CPUs. As an example, there is a high chance that data might be
cache'd and other CPUs can't see the change. In such cases,
if snoop control unit is enabled, data is synchoronized immediately
between CPUs and the changes are visible to other CPUs.

This driver provides functionality to enable SCU as well as enabling
user to know the following
- number of CPUs present
- is a particular CPU operating in SMP mode or AMP mode
- data cache size of a particular CPU
- does SCU has ACP port
- is L2CPRESENT

Some platforms are extremely memory constrained and must split BL31
between multiple non-contiguous areas in SRAM. Allow the NOBITS
sections (.bss, stacks, page tables, and coherent memory) to be placed
in a separate region of RAM from the loaded firmware image.

Because the NOBITS region may be at a lower address than the rest of
BL31, __RW_{START,END}__ and __BL31_{START,END}__ cannot include this
region, or el3_entrypoint_common would attempt to invalidate the dcache
for the entire address space. New symbols __NOBITS_{START,END}__ are
added when SEPARATE_NOBITS_REGION is enabled, and the dcached for the
NOBITS region is invalidated separately.

Erratum 1688305 is a Cat B erratum present in r0p0, r0p1 versions
of Hercules core. The erratum can be avoided by setting bit 1 of the
implementation defined register CPUACTLR2_EL1 to 1 to prevent store-
release from being dispatched before it is the oldest.
