[ Upstream commit 66f862563ed68717dfd84e808ca12705ed275ced ]
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.
