net: bcmgenet: handle UMAC_IRQ_MPD_R interrupt bit
Handle UMAC_IRQ_MPD_R interrupt bit in our workqueue to make sure that we properly re-configure the GENET adapter from Wake-on-LAN. bcmgenet_power_up() makes sure that we will not leave the UniMAC hardware in MagicPacket matching mode, since that would prevent any other packet from being received.
