sh: mac address through private data for sh_eth on ecovec24
Convert the ecovec24 board code to pass the mac address to the sh_eth driver using platform data. Also, remove the static clock to allow Runtime PM. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
