net: xpcs: allow 1000BASE-X to work with older XPCS IP
Older XPCS IP requires SGMII_LINK and PHY_SIDE_SGMII to be set when
operating in 1000BASE-X mode even though the XPCS is not configured for
SGMII. An example of a device with older XPCS IP is KSZ9477.
We already don't clear these bits if we switch from SGMII to 1000BASE-X
on TXGBE - which would result in 1000BASE-X with the PHY_SIDE_SGMII bit
left set.
It is currently believed to be safe to set both bits on newer IP
without side-effects.
