Implements a way to add platform specific power off code to a
Marvell Armada 8K platform.

Marvell Armada 8K boards can now add a board/system_power.c file
that contains a system_power_off() function.
This function can now send a command to a power management MCU or
other board periferals before shutting the board down.

I am working on a device that will be ported later, which has a
custom power management MCU that handles LEDs, board power and fans
and requires this separation.

NOTE for platform integrators:
   API `plat_psci_stat_get_residency()` third argument
   `last_cpu_idx` is changed from "signed int" to the
   "unsigned int" type.

Issue / Trouble points
1. cpu_idx is used as mix of `unsigned int` and `signed int` in code
with typecasting at some places leading to coverity issues.

2. Underlying platform API's return cpu_idx as `unsigned int`
and comparison is performed with platform specific defines
`PLAFORM_xxx` which is not consistent

Misra Rule 10.4:
The value of a complex expression of integer type may only be cast to
a type that is narrower and of the same signedness as the underlying
type of the expression.

Based on above points, cpu_idx is kept as `unsigned int` to match
the API's and low-level functions and platform defines are updated
where ever required

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.

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

This patch updates the functions to return negative values as error

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
