====================
net: phy: split at803x

This is the last patchset of a long series of cleanup and
preparation to make at803x better maintainable and permit
the addition of other QCOM PHY Families.

A shared library modules is created since many QCOM PHY share
similar/exact implementation and are reused.

This series doesn't introduce any new code but just move the
function around and introduce a new module for all the functions
that are shared between the 3 different PHY family.

Since the drivers are actually detached, new probe function are
introduced that allocate the specific priv struct for the PHYs.

After this patch, qca808x will be further generalized as LED
and cable test function are also used by the QCA807x PHYs.
This is just for reference and the additional function move will
be done on the relates specific series.

This is also needed in preparation for the introduction of
qca807x PHYs family and PHY package concept.
