net/mlx4_core: Enhance the catas flow to support device reset
This includes:
- resetting the chip when a fatal error is detected (the current code
does not do this).
- exposing the ability to enter error state from outside the catas code
by calling its functionality. (E.g. FW Command timeout, AER error).
- managing a persistent device state. This is needed to sync between
reset flow cases.
