wifi: ath12k: Initialize hal_ops through hal_init

Modularize the HAL layer by moving hal_ops from ab->hw_params into the
ab->hal. This reduces indirection and allows data path to access HAL ops
directly through the HAL context.

Initialize hal_ops via hal_init using a const table ath12k_hw_version_map.
This approach will be extended to register other HAL parameters during
init.

Remove ab->hw_params->hal_ops as it is no longer needed.
