From: Nachiket Kukade <kukaden@xxxxxxxxxxx>
First firmware dump attempt from user works fine, but firmware goes
into bad state after this. Subsequent attempts fails.
As required by the firmware dump implementation, this change writes
FW_DUMP_READ_DONE value to dump ctrl register to address this issue.
