Fix MISRA defects in xlat tables lib and SP805 driver

Set the function pointers in the console struct and the functions
they point to to const since they only need to be defined when
the console is being initialised and should not be changed after

We can enter and exit coherency without any software operations,
but HW_ASSISTED_COHERENCY has stronger implications that are
causing issues. Until these can be resolved, only use the weaker
WARMBOOT_ENABLE_DCACHE_EARLY flag.

When a platform enables its caches before it initializes the
GICC/GICR interface then explicit cache maintenance is not
needed. Remove these here.

If either USE_COHERENT_MEM or HW_ASSISTED_COHERENCY being true
should cause us to not enter the ifdef block, then the logic
is not correct here. Posibly bad use of De Morgan's law?
Fix this.

Add the various flags that are required to build the components needed
to enable the RAS feature on SGI575 platform. By default, all flags
are set to 0, disabling building of all corresponding components.

Add platform specific changes needed to add support for the RAS
feature on SGI575 platform, including adding a mapping for the
CPER buffer being used on SGI575 platform.

Add a platform specific handler for RAS interrupts and configure the
platform RAS interrupts for EL3 handling. The interrupt handler passes
control to StandaloneMM code executing in S-EL0, which populates the
CPER buffer with relevant error information. The handler subsequently
invokes the SDEI client which processes the information in the error
information in the CPER buffer. The helper functions
plat_sgi_get_ras_ev_map and plat_sgi_get_ras_ev_map_size would be
defined for sgi platforms in the subsequent patch, which adds sgi575
specific RAS changes.

The secure partition manager reserves chunks of memory which are used
for the S-EL0 StandaloneMM image and the buffers required for
communication between the Non-Secure world with the StandaloneMM
image. Add the memory chunks to relevant arrays for mapping the
regions of memory with corresponding attributes.

The SGI platforms need to allocate memory for CPER buffers. These
platform buffers would be placed between the shared reserved memory
and the per cpu stack memory, thus the need to redefine stack base
pointer for these platforms. This patch allows each board in ARM
platform to define the PLAT_SP_IMAGE_STACK_BASE.

Include arm_spm_def.h in the platform_def.h file. Without this
inclusion, we get build errors like

In file included from services/std_svc/spm/sp_setup.c:12:0:
services/std_svc/spm/sp_setup.c: In function 'spm_sp_setup':
services/std_svc/spm/sp_setup.c:61:57: error: 'PLAT_SPM_BUF_BASE'
  undeclared (first use in this function)
  write_ctx_reg(get_gpregs_ctx(ctx), CTX_GPREG_X0, PLAT_SPM_BUF_BASE);

Now that the platform_def.h includes arm_spm_def.h, remove inclusion
of platform_def.h in arm_spm_def.h to remove the circular dependency.

The board_arm_def.h header file needs to be included via the platform
definition header. Not doing so, results in a redefinition error of
PLAT_ARM_MAX_BL31_SIZE macro, if defined in the platform definition
file.
