igb: Workaround for igb i210 firmware issue

commit 4e684f59d760a2c7c716bb60190783546e2d08a1 upstream.

Sometimes firmware may not properly initialize I347AT4_PAGE_SELECT causing
the probe of an igb i210 NIC to fail. This patch adds an addition zeroing
of this register during igb_get_phy_id to workaround this issue.

Thanks for Jochen Henneberg for the idea and original patch.
