habanalabs/gaudi2: support abrupt device reset event

In certain scenarios, firmware might encounter a fatal event for
which a device reset is required. Hence, a proper notification
is needed for driver to be aware and initiate a reset sequence.

In secured environments the reset will be performed by firmware
without an explicit request from the driver.
