crypto: qat - enable power management for QAT GEN4
Add support for HW QAT Power Management (PM) feature.
This feature is enabled at init time (1) by sending an admin message to
the firmware, targeting the admin AE, that sets the idle time before
the device changes state and (2) by unmasking the PM source of interrupt
in ERRMSK2.
The interrupt handler is extended to handle a PM interrupt which
is triggered by HW when a PM transition occurs. In this case, the
driver responds acknowledging the transaction using the HOST_MSG
mailbox.
