Merge branch 'phy_ethtool_nway_reset'

Florian Fainelli says:

====================
net: phy: Centralize auto-negotation restart

This patch series centralizes how ethtool::nway_reset is implemented
by providing a PHYLIB function which calls into genphy_restart_aneg().

All drivers below are converted to use this new helper function. Some
other have specific requirements that make them not quite suitable for
a straight forward conversion.

There is another patch series which implements ethtool::nway_reset
using the helper function introduced that depends on this patch
series.
