net: dsa: mt7530: 1G can also support 1000BASE-X link mode
When using an external PHY connected using RGMII to mt7531 port 5, the
PHY can be used to used support 1000BASE-X connections. Moreover, if
1000BASE-T is supported, then we should allow 1000BASE-X as well, since
which are supported is a property of the PHY.
Therefore, it makes no sense to exclude this from the linkmodes when
1000BASE-T is supported.
