Merge branch 'phy-aquantia-improvements' 

Heiner Kallweit says:

====================
net: phy: aquantia: number of improvements

This patch series is based on work from Andrew. I adjusted and added
certain parts. The series improves few aspects of driver, no functional
change intended.

v2:
- add my SoB to patch 1
- leave kernel.h in in patch 2
