Thanks for pointing this out. These are the devicetrees which use any of 
the GPIOs for rgmii2 (GPIO 22 - 33).

mt7621_xzwifi_creativebox-v1.dts
mt7621_tplink_rexx0-v1.dtsi
mt7621_firefly_firewrt.dts

mt7621_wevo_w2914ns-v2.dtsi
mt7621_tplink_archer-x6-v3.dtsi
mt7621_netgear_ex6150.dts

I will send v2 where the pinctrl-0 property for ethernet is overwritten 
with only the rgmii1_pins and mdio_pins values for these devices.

Cheers.
