Ok, this means that the description of the original patch is wrong, because the
patch turns off the PHY_SWAP bit and it leaves the PYH_ADDR_SWAP bit set.
In theory, a simple
ath79_setup_ar933x_phy4_switch(false, false);
line should be enough to make it working, and the
ath79_eth0_data.phy_mask = BIT(0);
line should be dropped from the patch.

No, it makes no sense at all. The GE1 interface is always connected to MAC0 of
the built-in switch via GMII interface regardless of the state of the
PHY_SWAP/PHY_ADDR_SWAP bits.
