net: bcmgenet: Indicate MAC is in charge of PHY PM

Browse Source 
commit bc3410f250219660a7be032c01c954a53b2c26ab upstream.

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: fba863b816 ("net: phy: make PHY PM ops a no-op if MAC driver manages PHY PM")
