Subject: [PATCH net 1/3] net: atlantic: broken link status on old fw

Last code/checkpatch cleanup did a copy paste error where code from
firmware 3 API logic was moved to firmware 1 logic.

This resulted in FW1.x users would never see the link state as active.

Fixes: 7b0c342f1f67 ("net: atlantic: code style cleanup")
