net: systemport: add Wake-on-LAN support
Support for Wake-on-LAN using Magic Packet with or without SecureOn password is implemented doing the following: - setting the password to the relevant UniMAC registers - flagging the device as a wakeup source for the system, as well as its Wake-on-LAN interrupt - prepare the hardware for entering WoL mode - enabling the MPD interrupt to wake us The Device Tree binding documentation is also reflected to specify the third optional Wake-on-LAN interrupt line.
