[PATCH ath-next 14/17] wifi: ath12k: store and use MSI data per CE and DP interrupt group for QCN6432

[Aaradhana Sahu <aaradhana.sahu@oss.qualcomm.com>]

From: Sowmiya Sree Elavalagan <quic_ssreeela@quicinc.com>

Store MSI data values for each interrupt vector during configuration
and use them for ring setup on hybrid devices. Hybrid devices require
explicit MSI data values rather than calculated offsets.

Add ce_msi_data and dp_msi_data arrays to store values captured from
MSI descriptors. Use stored values for ring configuration on QCN6432,
ensuring hardware uses exact platform MSI allocated values.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.6-01243-QCAHKSWPL_SILICONZ-1
Tested-on: IPQ5332 hw1.0 AHB WLAN.WBE.1.6-01322-QCAHKSWPL_SILICONZ-1
Tested-on: QCN6432 hw1.0 AHB WLAN.WBE.1.6-01322-QCAHKSWPL_SILICONZ-1
