From: Karthikeyan Periyasamy <quic_periyasa@xxxxxxxxxxx>
Currently, all QMI target memory types share the same allocation
logic within the function ath12k_qmi_alloc_target_mem_chunk().
However, for Multi Link Operation (MLO), 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.
