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.
