[PATCH] net: phy: phy_ethtool_ksettings_set: Allow any supported speed

[Nikita Yushchenko]

When auto-negotiation is not used, allow any speed/duplex pair
supported by the PHY, not only 10/100/1000 half/full.

This enables drivers to use phy_ethtool_set_link_ksettings() in their
ethtool_ops and still support configuring PHYs for speeds above 1 GBps.

Also this will cause an error return on attempt to manually set
speed/duplex pair that is not supported by the PHY.
