crypto: qat - add fatal error notification

Browse Source 
BugLink: https://bugs.launchpad.net/bugs/2056354

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.
