[PATCH RFC net-next 4/9] net: stmmac: remove PCS "mode" pause handling

[Russell King (Oracle)]

Remove the "we always autoneg pause" forcing when the stmmac driver
decides that a "PCS" is present, which blocks passing the ethtool
pause calls to phylink when using SGMII mode.

This prevents the pause results being reported when a PHY is attached
using SGMII mode, or the pause settings being changed in SGMII mode.
There is no reason to prevent this.
