[PATCH 1/2] net: bcmasp: Indicate MAC is in charge of PHY PM

[Justin Chen]

From: Florian Fainelli <florian.fainelli@xxxxxxxxxxxx>

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.

Fixes: 490cb412007d ("net: bcmasp: Add support for ASP2.0 Ethernet controller")
