Subject: [PATCH 2/2] gianfar: Use the same initial values as the phy layer

From: Thomas Graziadei <thomas.graziadei@...cronenergy.com>

The phy layer sets the link status initially to 1 to also support phyless
systems, therefore we set the gianfar drivers initial link status also to
1. This prevents the gfar_update_link_state() method to be called when the
driver and phy have just been initialized but no link state change was
detected yet.
