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

Browse source 
[ Upstream commit 9f172134dd ]

Avoid the PHY library call unnecessarily into the suspend/resume
functions by setting phydev->mac_managed_pm to true. The SYSTEMPORT
driver essentially does exactly what mdio_bus_phy_resume() does by
calling phy_resume().

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