Subject: [RFC net-next 2/9] i40e: Remove unused i40e_blink_phy_link_led

From: "Dr. David Alan Gilbert" <linux@...blig.org>

i40e_blink_phy_link_led() was added in 2016 by
commit fd077cd3399b ("i40e: Add functions to blink led on 10GBaseT PHY")

but hasn't been used.

Remove it.

Signed-off-by: Dr. David Alan Gilbert <linux@...blig.org>
