Device index parameter is used as unique identifier for devices involved
in Inter-device MLO. It is also used to configure the MLO parameter within
the QMI host capability send request. While currently set to zero, future
logic will be added for inter device support to populate this parameter
with non-zero values.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
