From: Tomer Tayar <ttayar@habana.ai>
F/W events are enabled in a late phase of the device init, so an event for a PCIE access error during the init, can be received after the init is already done and considered as successful. A resulting device reset, which does the same H/W init, can end similarly with this event right after the reset is done and considered as successful, and a loop of this sequence can continue.
To avoid it mark the PCIE access error as a fatal event, so after 2 consecutive events no more resets will be done.
