net: bcmgenet: suspend and resume from Wake-on-LAN



Update bcmgenet_suspend() to prepare the hardware for being put into
Wake-on-LAN mode if the device can wakeup the system, and Wake-on-LAN is
enabled. Whether we resume from Wake-on-LAN or not, make sure that
bcmgenet_resume() disables the UniMAC MagicPacket matching mode and puts
the hardware in a state where it can receive all incoming packets.
