Remove BL32_BASE when building without SPD for FVP

Previously, when building TF without SPD support, BL2 tried to load a
BL32 image from the FIP and fails to find one, which resulted on
warning messages on the console. Even if there is a BL32 image in the
FIP it shouldn't be loaded because there is no way to transfer
control to the Secure Payload without SPD support.

The Makefile has been modified to pass a define of the form
SPD_${SPD} to the source code the same way it's done for PLAT. The
define SPD_none is then used to undefine BL32_BASE when BL32 is not
used to prevent BL2 from trying to load a BL32 image and failing,
thus removing the warning messages mentioned above.

Add support to load BL31 in DRAM

This patch adds an option to the ARM common platforms to load BL31 in the
TZC secured DRAM instead of the default secure SRAM.

To enable this feature, set `ARM_BL31_IN_DRAM` to 1 in build options.
If TSP is present, then setting this option also sets the TSP location
to DRAM and ignores the `ARM_TSP_RAM_LOCATION` build flag.

To use this feature, BL2 platform code must map in the DRAM used by
BL31. The macro ARM_MAP_BL31_SEC_DRAM is provided for this purpose.
Currently, only the FVP BL2 platform code maps in this DRAM.

Fix the inconsistencies in bl1_tbbr_image_descs[]

This patch fixes inconsistencies in bl1_tbbr_image_descs[]
and miscellaneous fixes in Firmware Update code.

Following are the changes:
* As part of the original FWU changes, a `copied_size`
field was added to `image_info_t`. This was a subtle binary
compatibility break because it changed the size of the
`bl31_params_t` struct, which could cause problems if
somebody used different versions of BL2 or BL31, one with
the old `image_info_t` and one with the new version.
This patch put the `copied_size` within the `image_desc_t`.
* EXECUTABLE flag is now stored in `ep_info.h.attr` in place
of `image_info.h.attr`, associating it to an entrypoint.
* The `image_info.image_base` is only relevant for secure
images that are copied from non-secure memory into secure
memory. This patch removes initializing `image_base` for
non secure images in the bl1_tbbr_image_descs[].
* A new macro `SET_STATIC_PARAM_HEAD` is added for populating
bl1_tbbr_image_descs[].ep_info/image_info.h members statically.
The version, image_type and image attributes are now
populated using this new macro.
* Added PLAT_ARM_NVM_BASE and PLAT_ARM_NVM_SIZE to avoid direct
usage of V2M_FLASH0_XXX in plat/arm/common/arm_bl1_fwu.c.
* Refactoring of code/macros related to SECURE and EXECUTABLE flags.

NOTE: PLATFORM PORTS THAT RELY ON THE SIZE OF `image_info_t`
OR USE the "EXECUTABLE" BIT WITHIN `image_info_t.h.attr`
OR USE THEIR OWN `image_desc_t` ARRAY IN BL1, MAY BE
BROKEN BY THIS CHANGE. THIS IS CONSIDERED UNLIKELY.

Allow multi cluster topology definitions for ARM platforms

The common topology description helper funtions and macros for
ARM Standard platforms assumed a dual cluster system. This is not
flexible enough to scale to multi cluster platforms. This patch does
the following changes for more flexibility in defining topology:

1. The `plat_get_power_domain_tree_desc()` definition is moved from
`arm_topology.c` to platform specific files, that is `fvp_topology.c`
and `juno_topology.c`. Similarly the common definition of the porting
macro `PLATFORM_CORE_COUNT` in `arm_def.h` is moved to platform
specific `platform_def.h` header.

2. The ARM common layer porting macros which were dual cluster specific
are now removed and a new macro PLAT_ARM_CLUSTER_COUNT is introduced
which must be defined by each ARM standard platform.

3. A new mandatory ARM common layer porting API
`plat_arm_get_cluster_core_count()` is introduced to enable the common
implementation of `arm_check_mpidr()` to validate MPIDR.

4. For the FVP platforms, a new build option `FVP_NUM_CLUSTERS` has been
introduced which allows the user to specify the cluster count to be
used to build the topology tree within Trusted Firmare. This enables
Trusted Firmware to be built for multi cluster FVP models.

ARM platforms: rationalise memory attributes of shared memory

The shared memory region on ARM platforms contains the mailboxes and,
on Juno, the payload area for communication with the SCP. This shared
memory may be configured as normal memory or device memory at build
time by setting the platform flag 'PLAT_ARM_SHARED_RAM_CACHED' (on
Juno, the value of this flag is defined by 'MHU_PAYLOAD_CACHED').
When set as normal memory, the platform port performs the corresponding
cache maintenance operations. From a functional point of view, this is
the equivalent of setting the shared memory as device memory, so there
is no need to maintain both options.

This patch removes the option to specify the shared memory as normal
memory on ARM platforms. Shared memory is always treated as device
memory. Cache maintenance operations are no longer needed and have
been replaced by data memory barriers to guarantee that payload and
MHU are accessed in the right order.

Rework use of interconnect drivers

interconnect peripherals.

Rework use of interconnect drivers

ARM Trusted Firmware supports 2 different interconnect peripheral
drivers: CCI and CCN. ARM platforms are implemented using either of the
interconnect peripherals.

This patch adds a layer of abstraction to help ARM platform ports to
choose the right interconnect driver and corresponding platform support.
This is as described below:

1. A set of ARM common functions have been implemented to initialise an
interconnect and for entering/exiting a cluster from coherency. These
functions are prefixed as "plat_arm_interconnect_". Weak definitions of
these functions have been provided for each type of driver.

2.`plat_print_interconnect_regs` macro used for printing CCI registers is
moved from a common arm_macros.S to cci_macros.S.

3. The `ARM_CONFIG_HAS_CCI` flag used in `arm_config_flags` structure
is renamed to `ARM_CONFIG_HAS_INTERCONNECT`.
