[PATCH net-next] net: phy: declare package-related struct members only if CONFIG_PHY_PACKAGE is enabled

[PATCH net-next] net: phy: declare package-related struct members only if CONFIG_PHY_PACKAGE is enabled

[Heiner Kallweit]

Now that we have an own config symbol for the PHY package module,
we can use it to reduce size of these structs if it isn't enabled.
