This reverts commit e5d527be7e6984882306b49c067f1fec18920735.
This software node change doesn't actually fix any current issues with the kernel, it is an improvement to the lookup process rather than fixing a live bug. It also causes a couple of regressions with shipping laptops, which relied on the label based lookup.
There is a fix for the regressions in mainline, the first 5 patches of [1]. However, those patches are fairly substantial changes and given the patch causing the regression doesn't actually fix a bug it seems better to just revert it in stable.
