====================
mlxfw: Improve error reporting and FW reactivate support

This patchset improves mlxfw error reporting to netlink and to
kernel log.

V2:
 - Use proper err codes, EBUSY/EIO instead of EALREADY/EREMOTEIO
 - Fix typo.

From Eran and me.

1) patch #1, Make mlxfw/mlxsw fw flash devlink status notify generic,
   and enable it for mlx5.

2) patches #2..#5 are improving mlxfw flash error messages by
reporting detailed mlxfw FSM error messages to netlink and kernel log.

3) patches #6,7 From Eran: Add FW reactivate flow to  mlxfw and mlx5
