ath11k: add CE interrupt support for QCN9074

Define host CE configuration for QCN9074 since the max CE count is six.
Available MSI interrupt is five so cannot able to map the ce_id directly
for the msi_data_idx. Added get_ce_msi_idx ops in ath11k_hif_ops to get
the CE MSI idx which is used to initialize the CE ring.

Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.4.0.1.r2-00012-QCAHKSWPL_SILICONZ-1
