crypto: qat - add support for ring pair level telemetry

Browse Source 
Expose through debugfs ring pair telemetry data for QAT GEN4 devices.

This allows to gather metrics about the PCIe channel and device TLB for
a selected ring pair. It is possible to monitor maximum 4 ring pairs at
the time per device.

For details, refer to debugfs-driver-qat_telemetry in Documentation/ABI.

This patch is based on earlier work done by Wojciech Ziemba.
