FWU: Add Firmware Update support in BL2U for ARM platforms

This patch adds support for Firmware update in BL2U for ARM
platforms such that TZC initialization is performed on all
ARM platforms and (optionally) transfer of SCP_BL2U image on
ARM CSS platforms.

BL2U specific functions are added to handle early_platform and
plat_arch setup. The MMU is configured to map in the BL2U
code/data area and other required memory.

Rework use of ARM GIC drivers on ARM platforms

Suport for ARM GIC v2.0 and v3.0 drivers has been reworked to create three
separate drivers instead of providing a single driver that can work on both
versions of the GIC architecture. These drivers correspond to the following
software use cases:

1. A GICv2 only driver that can run only on ARM GIC v2.0 implementations
e.g. GIC-400

2. A GICv3 only driver that can run only on ARM GIC v3.0 implementations
e.g. GIC-500 in a mode where all interrupt regimes use GICv3 features

3. A deprecated GICv3 driver that operates in legacy mode. This driver can
operate only in the GICv2 mode in the secure world. On a GICv3 system, this
driver allows normal world to run in either GICv3 mode (asymmetric mode)
or in the GICv2 mode. Both modes of operation are deprecated on GICv3
systems.

ARM platforms implement both versions of the GIC architecture. This patch adds a
layer of abstraction to help ARM platform ports chose the right GIC driver and
corresponding platform support. This is as described below:

1. A set of ARM common functions have been introduced to initialise the GIC and
the driver during cold and warm boot. These functions are prefixed as
"plat_arm_gic_". Weak definitions of these functions have been provided for
each type of driver.

2. Each platform includes the sources that implement the right functions
directly into the its makefile. The FVP can be instantiated with different
versions of the GIC architecture. It uses the FVP_USE_GIC_DRIVER build option
to specify which of the three drivers should be included in the build.

3. A list of secure interrupts has to be provided to initialise each of the
three GIC drivers. For GIC v3.0 the interrupt ids have to be further
categorised as Group 0 and Group 1 Secure interrupts. For GIC v2.0, the two
types are merged and treated as Group 0 interrupts.

The two lists of interrupts are exported from the platform_def.h. The lists
are constructed by adding a list of board specific interrupt ids to a list of
ids common to all ARM platforms and Compute sub-systems.

This patch also makes some fields of `arm_config` data structure in FVP redundant
and these unused fields are removed.

TBB: add Trusted Watchdog support on ARM platforms

This patch adds watchdog support on ARM platforms (FVP and Juno).
A secure instance of SP805 is used as Trusted Watchdog. It is
entirely managed in BL1, being enabled in the early platform setup
hook and disabled in the exit hook. By default, the watchdog is
enabled in every build (even when TBB is disabled).

A new ARM platform specific build option `ARM_DISABLE_TRUSTED_WDOG`
has been introduced to allow the user to disable the watchdog at
build time. This feature may be used for testing or debugging
purposes.

Specific error handlers for Juno and FVP are also provided in this
patch. These handlers will be called after an image load or
authentication error. On FVP, the Table of Contents (ToC) in the FIP
is erased. On Juno, the corresponding error code is stored in the
V2M Non-Volatile flags register. In both cases, the CPU spins until
a watchdog reset is generated after 256 seconds (as specified in
the TBBR document).

TBB: add platform API to read the ROTPK information

This patch extends the platform port by adding an API that returns
either the Root of Trust public key (ROTPK) or its hash. This is
usually stored in ROM or eFUSE memory. The ROTPK returned must be
encoded in DER format according to the following ASN.1 structure:

SubjectPublicKeyInfo ::= SEQUENCE {
algorithm AlgorithmIdentifier,
subjectPublicKey BIT STRING
}

In case the platform returns a hash of the key:

DigestInfo ::= SEQUENCE {
digestAlgorithm AlgorithmIdentifier,
keyDigest OCTET STRING
}

An implementation for ARM development platforms is provided in this
patch. When TBB is enabled, the ROTPK hash location must be specified
using the build option 'ARM_ROTPK_LOCATION'. Available options are:

- 'regs' : return the ROTPK hash stored in the Trusted
root-key storage registers.

- 'devel_rsa' : return a ROTPK hash embedded in the BL1 and
BL2 binaries. This hash has been obtained from the development
RSA public key located in 'plat/arm/board/common/rotpk'.

On FVP, the number of MMU tables has been increased to map and
access the ROTPK registers.

A new file 'board_common.mk' has been added to improve code sharing
in the ARM develelopment platforms.

Add SP804 delay timer support to the FVP BSP.

This commit simply provides the 3 constants needed by the SP804
delay timer driver and calls sp804_timer_init() in
bl2_platform_setup(). The BSP does not currently use the delay
timer functions.

Note that the FVP SP804 is a normal world accessible peripheral
and should not be used by the secure world after transition
to the normal world.
