Since commit
744d23c71af39c7d ("net: phy: Warn about incorrect
mdio_bus_phy_resume() state"), a warning splat is printed during system
resume with Wake-on-LAN disabled:
WARNING: CPU: 0 PID: 1197 at drivers/net/phy/phy_device.c:323 mdio_bus_phy_resume+0xbc/0xc8
As the Renesas Ethernet AVB driver already calls phy_{stop,start}() in
its suspend/resume callbacks, it is sufficient to just mark the MAC
responsible for managing the power state of the PHY.
Fixes:
