Merge branch 'bnxt_en-NS2-Nitro'

Michael Chan says:

====================
bnxt_en: Add support for NS2 Nitro.

This series adds support for the embedded version of the
ethernet controller (Nitro) in the North Star 2 SoC.  There are a number
of features not supported and a software workaround for a hardware rx
bug is required for Nitro A0.  Please review.
