net: bcmasp: Indicate MAC is in charge of PHY PM
[ Upstream commit 5b76d928f8b779a1b19c5842e7cabee4cbb610c3 ]
Avoid the PHY library call unnecessarily into the suspend/resume
functions by setting phydev->mac_managed_pm to true. The ASP driver
essentially does exactly what mdio_bus_phy_resume() does.
