Do you have a RT2880 Datasheet that describe the SYSCTL1 register in
detail? I'm asking because I don't really know if the bits do anything
for the RT2880 too. (I think the RT2880 also should have a way to control
whenever it's a RGMII/MII/RMII).

Because as far as I can tell, the RT3883/3662 code needs to be extended
to support the GE2 too. (This can be mostly copied from the existing
soc_mt7620 code). The RT3883/3662 just lacks the internal switch otherwise
it looks to be the same.
