It seems it was the other way around:
    BIG FAT WARNING: because the DTs were so far lying by not
    exposing the fact that the GPC block is actually the first
    interrupt controller in the chain, kernels with this patch
    applied wont have any suspend-resume facility when booted
    with old DTs, and old kernels with updated DTs won't even boot.

... perhaps combined with something else. I don't remember.

Nevertheless, the ugly DTS entries are just this - ugly. We should have
a way to remove them eventually.
