net: phy: mediatek: remove PHY mode check on MT7531

The function mt7531_phy_mode_supported in the DSA driver set supported
mode to PHY_INTERFACE_MODE_GMII instead of PHY_INTERFACE_MODE_INTERNAL
for the internal PHY, so this check breaks the PHY initialization:

mt7530 mdio-bus:00 wan (uninitialized): failed to connect to PHY: -EINVAL

Remove the check to make it work again.
