feat(arm): unify Linux kernel as BL33 handling

Streamlines and unifies how Arm platforms pass arguments to the Linux
kernel when it is loaded as BL33. It replaces the FVP specific macro
`FVP_HW_CONFIG_ADDR` with a common macro `ARM_HW_CONFIG_ADDR` for
accessing the device tree blob base address.

For FVP the DT address is set to use `ARM_PRELOADED_DTB_BASE` if
provided, falling back to a default address otherwise.

This provides a consistent mechanism for Arm platforms to define and
override the DTB base address used during kernel handoff. It reduces the
chance of misconfiguration, and simplifies platform integration.

feat(fvp): add GICv5 support

Factors out GICv3 specific code and replace it with GICv5. This can be
selected with FVP_USE_GIC_DRIVER=FVP_GICV5. Specifically, the FCONF
logic does not apply to GICv5

feat(fvp): add GICv5 support

Factors out GICv3 specific code and replace it with GICv5. This can be
selected with FVP_USE_GIC_DRIVER=FVP_GICV5. Specifically, the FCONF
logic does not apply to GICv5 as the bindings are completely different.

This patch does not include a device tree. This will be added at a later
date.

docs(fvp): restructure FVP platform documentation

The Arm FVP documentation has grown organically over the years. As a
result, it has become a big document, which can be difficult to digest.

Also,

docs(fvp): restructure FVP platform documentation

The Arm FVP documentation has grown organically over the years. As a
result, it has become a big document, which can be difficult to digest.

Also, the organization of some of the sections does not make sense. In
particular, all "Running on the ... FVP" sections live under a section
named "Booting a preloaded kernel image (Base FVP)". To illustrate this,
here is the current table of contents:

Arm Fixed Virtual Platforms (FVP)
Fixed Virtual Platform (FVP) Support
Arm FVP Platform Specific Build Options
Booting Firmware Update images
Booting an EL3 payload
Booting a preloaded kernel image (Base FVP)
Obtaining the Flattened Device Treesp
Running on the Foundation FVP with reset to BL1 entrypoint
Running on the AEMv8 Base FVP with reset to BL1 entrypoint
Running on the AEMv8 Base FVP (AArch32) with reset to BL1 entrypoint
Running on the Cortex-A57-A53 Base FVP with reset to BL1 entrypoint
Running on the Cortex-A32 Base FVP (AArch32) with reset to BL1 entrypoint
Running on the AEMv8 Base FVP with reset to BL31 entrypoint
Running on the AEMv8 Base FVP (AArch32) with reset to SP_MIN entrypoint
Running on the Cortex-A57-A53 Base FVP with reset to BL31 entrypoint
Running on the Cortex-A32 Base FVP (AArch32) with reset to SP_MIN entrypoint

This patch breaks down this document in sub-documents, which are now
included from the index file. The table of contents (ToC) reflects the
new documents hierarchy. The depth of the ToC has been reduced to
simplify the index page. Here is what it looks like now:

Arm Fixed Virtual Platforms (FVP)
Fixed Virtual Platform (FVP) Support
Arm FVP Platform Specific Build Options
Running on the Foundation FVP
Running on the AEMv8 Base FVP
Running on the Cortex-A57-A53 Base FVP
Running on the Cortex-A32 Base FVP (AArch32)
Booting Firmware Update images
Booting an EL3 payload
Booting a preloaded kernel image (Base FVP)

Apart from moving information around in separate files, this patch also
makes the following minor changes to the contents:

- Add a brief introduction about FVPs in the index page.
- Change some of the titles names for conciseness.
