Looks like u-boot was finally fixed and now assigns a
local-mac-address property to device nodes even if u-boot itself isn't
configured with a network driver. This is helpful since this means we
can have a static MAC address even if y-boot doesn't touch the
hardware.
Diff below adds the necessary code to dwge(4) to take advantage of this.
ok?
