e1000: fix sw fw sync on igb i210/i211
I finally had a look at the datasheet and spotted an additional register address difference between regular E1000 and i210/i211 chips. This patch fixes this and now successfully works on programmed i210/i211 as well as unprogrammed i211. Signed-off-by: Marcel Ziswiler <marcel@ziswiler.com>
