gianfar: Enable all wol ports as wakeup event sources
Not all the eTSECs have an active clock by default
when the devices enter suspend state (i.e. sleep
power state). This property is however configurable,
and all the eTSECs with wake-on-lan capabilities
can be enabled as wakeup event sources.
Use the PMC API to enable all the eTSEC ports, which
are capable of wake-on-lan, as wakeup event sources.
