RTL8116af is sfp mode. Phylink uses pcs to get the link status from its
serdes reg, instead of standard phy reg. Speed and duplex are hardcoded
to 1000Mbps Full-Duplex. Also, RTL8116af doesn't have internal phy, so
we add some checks to ensure that tp->phydev is not empty when we need it.
In rtl_hw_start_8117(), the MAC calibration for register 0xd412 relies
on reading the internal PHY register 0x0c42. Since RTL8116af does not
have an internal PHY, this calibration step is intentionally bypassed.
