Other than this is somewhat more "correct", is it really needed for those
boards? Because it breaks compatibility with older kernels, so when we
update the DTs in U-Boot, we run into problems (again).

IIUC this series is about the OPi3 & friends, which didn't work with older
kernels anyway, so can we just skip this patch (and 5/6), to just enable
the boards that didn't work before?

Cheers,
Andre
