Expose FW counters statistics by providing the "fw_counters" file under debugfs. Currently the statistics include the number of requests sent to the FW and the number of responses received from the FW for each Acceleration Engine, for all the QAT product line. This patch is based on earlier work done by Marco Chiappero.
