[PATCH net-next] net: phy: probe the PHY before determining the supported features

[Heiner Kallweit <hkallweit1@gmail.com>]

From: Andrew Lunn <andrew@lunn.ch>
We will soon support asking the PHY at runtime to determine what
features it supports, rather than forcing it to be compile time.
But we should probe the PHY first. So probe the phy driver earlier.
