net: phy: provide phy driver start/stop hooks
Provide phy driver start/stop hooks so that the PHY driver knows when the network driver is starting or stopping. This will be used for the Marvell 10G driver so that we can sanely refuse to start if the PHYs firmware is not present, and also so that we can sanely support SFPs behind the PHY.
