crypto: qat - fix ring to service map for QAT GEN4

Browse source

commit a238487f79 upstream.

The 4xxx drivers hardcode the ring to service mapping. However, when
additional configurations where added to the driver, the mappings were
not updated. This implies that an incorrect mapping might be reported
through pfvf for certain configurations.

Add an algorithm that computes the correct ring to service mapping based
on the firmware loaded on the device.

[Giovanni: backport to 6.1.y, conflict resolved simplifying the logic
in the function get_ring_to_svc_map() as the QAT driver in v6.1 supports
only limited configurations (crypto only and compression).  Differs from
upstream as the ring to service mapping is hardcoded rather than being
dynamically computed.]
