net: bcmgenet: power down and up GPHY during suspend/resume
In case the interface is not used, power down the integrated GPHY during suspend. Similarly to bcmgenet_open(), bcmgenet_resume() powers on the GPHY prior to any UniMAC activity. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
