The 802.3bz standard defines 2 modes based on the NBASET alliance work
that allow to use 2.5Gbps and 5Gbps speeds on Cat 5e, 6 and 7 cables.

This series adds the necessary infrastructure to handle these modes with
C45 PHYs. This series was originally part of a bigger one, that has
seen 2 iterations [1] [2] that added support for these modes on Marvell
Alaska PHYs.

Following some discussions with Heiner and Andrew [3], we decided to
split-out the generic parts so that we can work together on the
following steps to get these mode fully working with Aquantia and
Marvell PHYS.

The first 3 patches are reworking some of the internal network phy
infrastructure to handle the new modes in a more generic way.

The 4th patch adds all the C45 register definition and accesses that
follows the 802.3bz standard to support 2.5GBASET and 5GBASET.

I'll give Andrew, Florian, and Heiner a chance to review this series.

Series applied, thanks Maxime.
