QAT devices implement a mechanism that allows them to go autonomously to a low power state depending on the load. Expose power management info by providing the "pm_status" file under debugfs. This includes PM state, PM event log, PM event counters, PM HW CSRs, per-resource type constrain counters and per-domain power gating status specific to the QAT device. This information is retrieved from (1) the FW by means of ICP_QAT_FW_PM_INFO command, (2) CSRs and (3) counters collected by the device driver. In addition, add logic to keep track and report power management event interrupts and acks/nacks sent to FW to allow/prevent state transitions.
