Currently when phy device is created the link variable is initialized to 1 which denoted phy link is already up. On a power reset there is no issue as phy status register link status will not be set, so phy auto negotiate will be started. But when a cpu reset is issued (ex: dra72x-evm) phy's link status bit is already set which leads to assume that link is already setup in genphy_update_link() initial check which results in ehternet not working. So do not assume that link is already up and on phy device create set link to zero. This is verified on dra72x-evm.
