crypto: qat - add fatal error notification
Notify a fatal error condition and optionally reset the device in
the following cases:
* if the device reports an uncorrectable fatal error through an
interrupt
* if the heartbeat feature detects that the device is not
responding
This patch is based on earlier work done by Shashank Gupta.
