[PATCH net-next 1/2] bnx2x: Add MBI version to ethtool driver query output.

[Sudarsana Reddy Kalluru]

The patch populates the MBI version in the ethtool driver query data.
Adding 'extended_dev_info_shared_cfg' structure describing the nvram
structure, this is required to access the mbi version string.
