From: Liad Kaufman <liad.kaufman@xxxxxxxxx>
To stop and start the FW monitor in the 7000 HW
family we need to use a different bit, otherwise
after stopping it for the first time - it won't
get restarted. Use the correct bitmask.
Note: This fix is only for DRAM collection mode.
For other modes, an additional fix will be
needed.
