====================
net: dsa: convert two drivers to phylink_generic_validate()

Patches 1 to 3 update core DSA code to allow drivers to be converted,
and patches 4 and 5 convert hellcreek and lantiq to use this (both of
which received reviewed-by from their maintainers.) As the rest have
yet to be reviewed by their maintainers, they are not included here.

Patch 1 had a request to change the formatting of it; I have not done
so as I believe a patch should do one change and one change only -
reformatting it is a separate change that should be in its own patch.
However, as patch 2 gets rid of the reason for reformatting it, it
would be pointless, and pure noise to include such an intermediary
patch.

Instead, I have swapped the order of patches 2 and 3 from the RFC
series.
