The logic that generates the compression templates, which are used by to submit compression requests to the QAT device, is very similar between QAT devices and diverges mainly on the HW generation-specific configuration word. This makes the logic that generates the compression and decompression templates common between GEN2 and GEN4 devices and abstracts the generation-specific logic to the generation-specific implementations. The adf_gen2_dc.c and adf_gen4_dc.c have been replaced by adf_dc.c, and the generation-specific logic has been reduced and moved to adf_gen2_hw_data.c and adf_gen4_hw_data.c. This does not introduce any functional change.
