crypto: qat - add auto reset on error

Browse Source 
Expose the `auto_reset` sysfs attribute to configure the driver to reset
the device when a fatal error is detected.

When auto reset is enabled, the driver resets the device when it detects
either an heartbeat failure or a fatal error through an interrupt.

This patch is based on earlier work done by Shashank Gupta.
