qca-wifi: Assign agile detector id based on true 160MHz

For Pine chip, where true 160MHz (single detector for 160MHz)
is supported, the agile detector ID is 1 (instead of 2 for
chipsets like Hawkeye with two primary 80MHz detectors).
Assign the dfs_agile_detector_id to the proper value based on
true 160MHz capability.

Introduce a new API to get the agile_detector_id based on the
chip's capability. Use the new API to get the agile_detector_id
instead of using the existing enum.
