wifi: ath12k: Introduce device index

Browse Source 
Introduce a device index parameter in the ath12k_base structure. This
value 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
