[PATCH net-next v2 4/7] net: phy: smsc: add flag edpd_mode_set_by_user

[Heiner Kallweit <hkallweit1@gmail.com>]

Add flag edpd_mode_set_by_user in preparation of adding edpd phy tunable
support. This flag will allow users to override the default behavior
of edpd being disabled if interrupt mode is used.
