feat(fvp): extend image decryption support for FVP

Add encryption IO layer to be stacked above FIP IO layer for optional
encryption of the BL31 and BL32 images in case the ENCRYPT_BL31 or
ENCRYPT_BL32 build flag is set.

Enable decryption support for FVP through setting the DECRYPTION_SUPPORT
build flag. "DECRYPTION_SUPPORT = aes_gcm" is set to perform authenticated
decryption using AES-GCM algorithm.

feat(fwu): pass a const metadata structure to platform routines

The metadata structure copy is passed to the platform routine to set
the image source to boot the platform from. This is done by reading
the metadata structure. Pass the metadata as a read-only copy to the
routine -- the routine only needs to consume the metadata values and
should not be able to update the metadata fields.

Merge the previously introduced arm_fconf_io_storage into arm_io_storage. This
removes the duplicate io_policies and functions definition.

This patch:
- replace arm_io_storage.c with the content of arm_fconf_io_storage.c
- rename the USE_FCONF_BASED_IO option into ARM_IO_IN_DTB.
- use the ARM_IO_IN_DTB option to compile out io_policies moved in dtb.
- propagate DEFINES when parsing dts.
- use ARM_IO_IN_DTB to include or not uuid nodes in fw_config dtb.
- set the ARM_IO_IN_DTB to 0 by default for fvp. This ensure that the behavior
of fvp stays the same as it was before the introduction of fconf.

Sanitise includes across codebase

Enforce full include path for includes. Deprecate old paths.

The following folders inside include/lib have been left unchanged:

- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}

The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).

For example, this patch had to be created because two headers were
called the same way: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a282 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca33988b9 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.

Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

Merge pull request #1386 from soby-mathew/sm/dyn_bl31

Extend dynamic configuration

FVP: Add dummy configs for BL31, BL32 and BL33

The config files are placeholders and do not have any useful bindings
defined

FVP: Add dummy configs for BL31, BL32 and BL33

This patch adds soc_fw_config, tos_fw_config and nt_fw_config to the FVP.
The config files are placeholders and do not have any useful bindings
defined. The tos_fw_config is packaged in FIP and loaded by BL2 only
if SPD=tspd. The load address of these configs are specified in tb_fw_config
via new bindings defined for these configs. Currently, in FVP, the
soc_fw_config and tos_fw_config is loaded in the page between BL2_BASE
and ARM_SHARED_RAM. This memory was typically used for BL32 when
ARM_TSP_RAM_LOCATION=tsram but since we cannot fit BL32 in that
space anymore, it should be safe to use this memory for these configs.
There is also a runtime check in arm_bl2_dyn_cfg_init() which ensures
that this overlap doesn't happen.

The previous arm_dyn_get_hwconfig_info() is modified to accept configs
other than hw_config and hence renamed to arm_dyn_get_config_load_info().
The patch also corrects the definition of ARM_TB_FW_CONFIG_LIMIT to be
BL2_BASE.
