FVP: Support Base FVP RevC
Revision C of the Base FVP has the same memory map as earlier revisions,
but has the following differences:
- Implements CCI550 instead of CCI400,
- Has a single instantiation of SMMUv3,
- CPU MPIDs are shifted left by one level, and has MT bit set in them.
The correct interconnect to program is chosen at run time based on the
FVP revision. Therefore, this patch implements FVP functions for
interconnect programming, rather than depending on ARM generic ones. The
macros used have been renamed to reflect this change.
Additionally, this patch initializes SMMUv3 as part of FVP early
platform setup.
New ARM config flags are introduced for feature queries at run time.

FVP: Add support for multi-threaded CPUs
ARM CPUs with multi-threading implementation has more than one
Processing Element in a single physical CPU. Such an implementation will
reflect the following changes in the MPIDR register:
- The MT bit set;
- Affinity levels pertaining to cluster and CPUs occupy one level
higher than in a single-threaded implementation, and the lowest
affinity level pertains to hardware threads. MPIDR affinity level
fields essentially appear shifted to left than otherwise.
The FVP port henceforth assumes that both properties above to be
concomitant on a given FVP platform.
To accommodate for varied MPIDR formats at run time, this patch
re-implements the FVP platform-specific functions that translates MPIDR
values to a linear indices, along with required validation. The same
treatment is applied for GICv3 MPIDR hashing function as well.
An FVP-specific build option FVP_MAX_PE_PER_CPU is introduced which
specifies the maximum number of threads implemented per CPU. For
backwards compatibility, its value defaults to 1.

FVP: Do not map DEVICE2 memory range when TBB is disabled
The DEVICE2 memory range is needed to access the Root of Trust Public

so it's safer to not map it in this case. This also saves one level-2
page table in each of BL1 and BL2 images.
Also add some comments.

ARM plat changes to enable CryptoCell integration
This patch makes the necessary changes to enable ARM platform to
successfully integrate CryptoCell during Trusted Board Boot. The
changes are as follows:
* A new build option `ARM_CRYPTOCELL_INTEG` is introduced to select
the CryptoCell crypto driver for Trusted Board boot.
* The TrustZone filter settings for Non Secure DRAM is modified
to allow CryptoCell to read this memory. This is required to
authenticate BL33 which is loaded into the Non Secure DDR.
* The CSS platforms are modified to use coherent stacks in BL1 and BL2
when CryptoCell crypto is selected. This is because CryptoCell makes
use of DMA to transfer data and the CryptoCell SBROM library allocates
buffers on the stack during signature/hash verification.

juno/aarch32: Restore `SCP_BOOT_CFG_ADDR` to the cold boot value
Before BL2 loads the SCP ram firmware, `SCP_BOOT_CFG_ADDR` specifies
the primary core. After the SCP ram firmware has started executing,
`SCP_BOOT_CFG_ADDR` is modified. This is not normally an issue but
the Juno AArch32 boot flow is a special case. BL1 does a warm reset
into AArch32 and the core jumps to the `sp_min` entrypoint. This is
effectively a `RESET_TO_SP_MIN` configuration. `sp_min` has to be
able to determine the primary core and hence we need to restore
`SCP_BOOT_CFG_ADDR` to the cold boot value before `sp_min` runs.
This magically worked when booting on A53 because the core index was
zero and it just so happened to match with the new value in
`SCP_BOOT_CFG_ADDR`.

Introduce the build options ERRATA_A53_835769 and ERRATA_A53_843419.
Enable both of them for Juno.
Apply the 835769 workaround as following:
* Compile with -mfix-cortex-a53-835769
* Link with --fix-cortex-a53-835769
Apply the 843419 workaround as following:
* Link with --fix-cortex-a53-843419
The erratum 843419 workaround can lead the linker to create new sections
suffixed with "*.stub*" and 4KB aligned. The erratum 835769 can lead the
linker to create new "*.stub" sections with no particular alignment.
Also add support for LDFLAGS_aarch32 and LDFLAGS_aarch64 in Makefile for
architecture-specific linker options.
