net: bcmgenet: Indicate MAC is in charge of PHY PM
Avoid the PHY library call unnecessarily into the suspend/resume functions by
setting phydev->mac_managed_pm to true. The GENET driver essentially does
exactly what mdio_bus_phy_resume() does by calling phy_init_hw() plus
phy_resume().
Fixes: fba863b81604 ("net: phy: make PHY PM ops a no-op if MAC driver manages PHY PM")
