However, for Multi-Link Operation (MLO), the firmware requests a new MLO global memory region. This memory is shared across different firmware (SoC) participating in the MLO. To accommodate this logic change, refactor ath12k_qmi_alloc_target_mem_chunk() and introduce a helper function ath12k_qmi_alloc_chunk() for memory chunk allocation. Subsequent patch will add MLO global memory allocation logic.
