Add support for reading SFP module info and digital diagnostic monitoring data if supported by the module. The only Aquantia controller without an integrated PHY is the AQC100 which belongs to the B0 revision, that's why it's only implemented there. The register information was extracted from a diagnostic tool made publicly available by Dell, but all code was written from scratch by me. This has been tested to work with a variety of both optical and direct attach modules I had lying around and seems to work fine with all of them, including the diagnostics if supported by an optical module. All tests have been done with an AQC100 on an TL-NT521F card on firmware version 3.1.121 (current at the time of this patch).
