[PATCH v2 13/22] wifi: ath12k: remap CE register space for IPQ5332

[Raj Kumar Bhagat]

From: Balamurugan S <quic_bselvara@xxxxxxxxxxx>

For IPQ5332 CE register space is moved out of WCSS region and the
space is not contiguous. Hence, add hardware params (ce_ie_addr &
ce_remap) for IPQ5332. These parameters would be used by Ath12k
AHB driver to remap the CE registers to a new space for accessing
them.

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
