crypto: qat - add admin msgs for telemetry
Extend the admin interface with two new public APIs to enable
and disable the telemetry feature: adf_send_admin_tl_start() and
adf_send_admin_tl_stop().
The first, sends to the firmware, through the ICP_QAT_FW_TL_START
message, the IO address where the firmware will write telemetry
metrics and a list of ring pairs (maximum 4) to be monitored.
It returns the number of accelerators of each type supported by
this hardware. After this message is sent, the firmware starts
periodically reporting telemetry data using by writing into the
dma buffer specified as input.
The second, sends the admin message ICP_QAT_FW_TL_STOP
which stops the reporting of telemetry data.
This patch is based on earlier work done by Wojciech Ziemba.
