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.
