bnxt_en: Store the running firmware version code.
We currently only store the firmware version as a string for ethtool and devlink info. Store it also as a version code. The next 2 patches will need to check the firmware major version to determine some workarounds. We also use the 16-bit firmware version fields if the firmware is newer and provides the 16-bit fields.
