====================
net: renesas: set 'mac_managed_pm' at probe time

When suspending/resuming an interface which was not up, we saw mdiobus
related PM handling despite 'mac_managed_pm' being set for RAVB/SH_ETH.
Heiner kindly suggested the fix to set this flag at probe time, not at
init/open time. I implemented his suggestion and it works fine on these
two Renesas drivers.
