Subject: [PATCH] net: phy: mediatek: remove PHY mode check on MT7531

Patch-mainline: v5.17-rc5
References: git-fixes
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.
