p2771-0000: Pass Ethernet MAC to the kernel

Pass the ethernet MAC address to the kernel upon boot. This passes both
the local-mac-address property (as passed to U-Boot from cboot) and the
currently set MAC address via the mac-address property. The latter will
only be set if it is different from the address that was already passed
via the local-mac-address property.
