fix(versal2): buffer overflow due to missing bounds check

Add bounds check before accessing `rsvnodes`. Currently check is on
`rsv_count` instead of the loop index `i`, so the guard never trips
during the first pass. If `/reserved-memory` has more than
`MAX_RESERVE_ADDR_INDICES` subnodes, the code writes past the end
of the fixed-size `rsvnodes` array.

feat(amd): custom package linker infra

Add linker script consolidation framework for custom packages
integrated with TF-A.

- Implement two-stage preprocessing for custom linker scripts
- Auto-discover custom_pkg.ld.S files in package directories
- Create linker script template (plat.ld.S.tpl) for consolidation
- Support normalized absolute path resolution for multiple packages
- Generate final plat.ld.S by preprocessing template with custom scripts

The framework automatically discovers and preprocesses custom package
linker scripts, expanding package-specific macros before inclusion in
the final consolidated linker script. This enables multiple packages
to define custom memory regions and sections without conflicts.

feat(amd): support multiple custom packages

Add support for including multiple custom packages to be built and
linked with TF-A for AMD platforms. This allows flexible integration
of multiple custom service implementations.

- Introduce custom_pkg.mk for custom package integration
- Create custom_svc_stub.c with default stub implementations
- Refactor platform.mk to conditionally include custom packages
- Support multiple package paths via space/semicolon-separated
CUSTOM_PKG_PATH

The framework handles discovery and inclusion of custom_pkg.mk files
from each package directory, providing flexibility for platform-specific
customizations without modifying TF-A core code.

feat(versal2): remove handoff entry from tl

In Versal Gen 2, handoff passing mechanism is via transfer list.
Transfer list is packaged with handoff addresses of BL32, BL33 along
with DT blob as part of it.
Once TF-A process the hand off details, rest of the components
(primarily U-Boot) should not parse these details at non-secure world.

Post retrieval of handoff information, remove entry point structures
catering to OP-TEE and U-Boot.

build(handoff)!: switch to LibTL submodule

Removes in-tree Transfer List implementation and updates all references
to use the external LibTL submodule. Updates include paths, Makefile
macros, and platform integration logic to link with LibTL as a static
library.

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
issues after migrating to the latest version of TF-A.

refactor(versal2): guard handoff logic w/ build flag

Prepare for environments where the Firmware Handoff (LibTL) submodule
may not be available. Wrap all Transfer List dependent logic in `#if
TRANSFER_LIST` guards, ensuring the platform can build and run without
the submodule.

This is useful for builds not integrating the firmware handoff
mechanism.
