net: phy: keep track of the PHY suspend state

Browse source 
In order to avoid double calls to phydev->drv->suspend and resume, keep
track of whether the PHY has already been suspended as a consequence of
a successful call to phy_suspend(). We will use this in our MDIO bus
suspend/resume hooks to avoid a double suspend call.
