net: ethernet: xgbe: re-add aneg to supported features in PHY quirks

Browse Source 
In 4.19, before the switch to linkmode bitmaps, PHY_GBIT_FEATURES
included feature bits for aneg and TP/MII ports.

				 SUPPORTED_TP | \
				 SUPPORTED_MII)

				 SUPPORTED_10baseT_Full)

				 SUPPORTED_100baseT_Full)

				 SUPPORTED_1000baseT_Full)

				 PHY_100BT_FEATURES | \
				 PHY_DEFAULT_FEATURES)

				 PHY_1000BT_FEATURES)

Referenced commit expanded PHY_GBIT_FEATURES, silently removing
PHY_DEFAULT_FEATURES. The removed part can be re-added by using
the new PHY_GBIT_FEATURES definition.
Not clear to me is why nobody seems to have noticed this issue.

I stumbled across this when checking what it takes to make
phy_10_100_features_array et al private to phylib.
