Revert "FPv2: fingerprint on all FW combinations" (#25417)

* Revert "FPv2: fingerprint on all FW combinations (#25204)"

This reverts commit c7e0622fa5bbf3ed8b000c86666f54f2b0a8c63d.

* Revert "Revert "FPv2: fingerprint on all FW combinations (#25204)""

This reverts commit bb68b7bc1c.

* For breaking, match only with current brand's FW

* Add comment for fuzzy matching

* fingerprint (online) only using FW from that brand

* test_fw_query_on_routes fingerprints like online

* extend match_fw_to_car to work for test_fw_query_on_routes

* Apply suggestions from code review
