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).

Here we add a number of ethtool private flags
to allow enabling various loopbacks on HW.
Thats useful for verification and bringup works.
