Add Qualcomm SMEM driver for OP-TEE. Structure the implementation as a platform-independent common layer (qti_smem.c/h), a TEE-specific platform abstraction layer (qti_smem_plat.c/h), and a clean public API. qti_smem_init() - initialize driver, validate TOC and map partitions qti_smem_host_id() - construct a SMEM host identifier qti_smem_lookup() - look up an existing SMEM item by host and item ID AI Usage: This contribution was developed, designed, implemented, and validated by the authors. AI-assisted tools were used only to help with code review, documentation drafting, commit message refinement, and general development productivity.
