fix(arm): move lfa componet header to common and fix the helper

Move the FVP LFA component definitions to include/plat/arm/common/
so they can be shared by all Arm platforms, and update include
paths accordingly.

On FVP, rename the input parameter to lfa_component_id to match
the function declaration, and fix callers to pass the component
ID (not image_id) to the prime-complete helper.

fix(arm): don't override the gic redistributor frames

Patch 75170704c made an oversight - it would provide a default value for
the gicr_frames variable but would always set to it, regardless of
whether the platform might want to use something different. The thinking
was to provide a default and then let each platform override it, however
the order was swapped.

To fix this, put the gic_set_gicr_frames() in bl31_platform_setup()
rather than arm_bl31_platform_setup(). This way, platforms that use the
default can still enjoy it automatically pulled in from common code,
platforms that need fully custom gicr_frames can simply set it, and
platforms that override bl31_platform_setup() for unrelated reasons only
have to redo the call to gic_set_gicr_frames(). This has a tiny benefit
over the old approach in that there will never be 2 gicr_frames arrays.

Introduce a macro guard so platform coherency functions are only

enable HW-assisted coherency by default, so compiling empty

This refactor removes those empty functions for Arm CSS platforms.

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.

fix(arm): re-enable console by default in BL31

In c997a8d, the common `arm_bl31_early_platform_setup` function
underwent a consolidation of two large preprocessor branches that were
conditional on whether or not Transfer List support is enabled.

This function would initialise the console via `arm_console_boot_init`
*only* if Transfer List support was disabled. During the consolidation,
this call was removed, such that the behaviour was the same for both
branches.

However, the common `bl31_early_platform_setup2` implementation was not
updated to reflect this change, and so platforms that a) relied on this
common implementation and b) did not enable Transfer List support no
longer initialise the console in BL31.

This change ensures that the common implementation correctly initialises
the console during early BL31 boot.

When RESET_TO_BL31 is defined, BL31 is the reset vector and no

Therefore, the arguments arg0 to arg3 passed to

so are not necessarily initialized to zero.

refactor(gicv3): clarify redistributor base address usage with USE_GIC_DRIVER=3

The GICv3 driver has 2 methods of discovering the redistributors:
a) via setting gicr_base - done at boot and assumes all GICR frames are
contiguous. This is the original method.

b) via gicv3_rdistif_probe() - called from platform code and requires
gicr_base == 0. It relaxes the requirement for frames to be
contiguous, like in a multichip configuration, and defers the
discovery to core bringup. This was introduced later.

Configurations possible with option a) are also possible with option b)
with only slightly different behaviour. USE_GIC_DRIVER=3 inherited
option b) from plat_gicv3_base.c and as such option a) is unusable.
However, it is unclear from code how this should be used. Clarify this
by requiring platforms initialise with gic_set_gicr_frames() and
adding relevant comments.

Also rename plat_arm_override_gicr_frames() to gic_set_gicr_frames() as
this is not plat arm specific and a part of the generic GIC driver.

If you cloned TF-A without the `--recurse-submodules` flag, you can
ensure that this submodule is present by running:

git submodule update --init --recursive

BREAKING-CHANGE: LibTL is now included in TF-A as a submodule.
Please run `git submodule update --init --recursive` if you encounter
