Major changes:
Update bloblist to align to Firmware Handoff spec v0.9 (https://github.com/FirmwareHandoff/firmware_handoff).
Implement Qemu-Arm platform custom functions to retrieve the bloblist (aka. Transfer List) from previous loader via boot arguments when CONFIG_OF_BOARD option is enabled.
If a board provides both custom functions for getting the bloblist and the address of external FDT, the FDT inside the bloblist will be prioritized during FDT setup.
The patch set is tested with previous done TF-A/OP-TEE patches through a complete Firmware Handoff cycle (BL2, BL31, BL32, BL33). TF-A Patches: feat(handoff): introduce firmware handoff library (https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/22215) feat(qemu): implement firmware handoff on qemu (https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/22178) feat(handoff): enhance transfer list library (https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/23776) feat(optee): enable transfer list in opteed (https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/23777) feat(qemu): enable transfer list to BL31/32 (https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/23778) OP-TEE Patch: Firmware handoff (https://github.com/OP-TEE/optee_os/pull/6308) fixup of transfer list entry overriding (https://github.com/OP-TEE/optee_os/pull/6461)
