[PATCH ath-next 17/17] wifi: ath12k: Add QCN6432 AHB support

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

Add AHB support for QCN6432 by adding its hardware descriptor and
device-tree compatible entry.

QCN6432 uses a hybrid bus where the CE memory is handled through the
PCI interface. Skip the CE remapping and cleanup in the AHB resource
initialization and deinitialization for hybrid bus devices.

Also add the UserPD mappings required for the QCN6432 devices.

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
