I believe defconfig is still mostly for us and the patch fits this
purpose - you need these to fully use mentioned upstream hardware.

I learnt that few distros (I think Fedora) use defconfig directly
instead of customizing it like Ubuntu does, so anyway maybe we should
enable everything for given hardware.
