Merge branch 'dsa-validate-remove'

Russell King says:

====================
net: dsa: remove validate method

These three patches remove DSA's phylink .validate method which becomes
unnecessary once the last two drivers provide phylink capabilities,
which this patch set adds. Both of these are best guesses.
