Subject: [PATCH net-next] net: ethernet: mediatek: use [get|set]_link_ksettings

From: Sean Wang <sean.wang@...iatek.com>

1) use new api [get|set]_link_ksettings instead
of [get|set]_settings old ones.

2) dev->phydev is sure being ready before calling
these callbacks, so removing all the sanity check
if it is existing.
