Subject: [PATCH ath-next v12 02/13] wifi: ath12k: fix incorrect CE
 addresses

From: Balamurugan S <quic_bselvara@...cinc.com>

In the current ath12k implementation, the CE addresses
CE_HOST_IE_ADDRESS and CE_HOST_IE_2_ADDRESS are incorrect. These
values were inherited from ath11k, but ath12k does not currently use
them.

However, the Ath12k AHB support relies on these addresses. Therefore,
correct the CE addresses for ath12k.

Tested-on: IPQ5332 hw1.0 AHB WLAN.WBE.1.3.1-00130-QCAHKSWPL_SILICONZ-1
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.1.1-00210-QCAHKSWPL_SILICONZ-1
