Some logic are similar for ATU or VLAN handling but then they added bits
in the middle of the register and moved some in other place.

Happy of being contradicted but from what I checked adapting the mtk
code would introduce lots of condition and wrapper and I feel it would
be actually worse than keeping the 2 codebase alone.

Would love some help by mt7530 to catch some very common case.
