[PATCH ath12k-ng 13/13] wifi: ath12k: Remove HAL define dependencies from shared AHB code

[Kiran Venkatappa]

Eliminate HAL-specific defines from the shared AHB implementation.
Store the WFSS register base-already available in hw_params via the
ce_remap structure-in the AHB context and access it directly.
Add the CMEM offset to the ce_remap structure and use it consistently in
shared code. Improve modularity by removing hardware abstraction layer
dependencies from common code paths and enable cleaner separation of
target-specific logic

Tested-on: IPQ5332 hw1.0 AHB WLAN.WBE.1.3.1-00130-QCAHKSWPL_SILICONZ-1
