I don't intend applying these two patches.

For Dalmore, there are two SKUs, one using KBC and one using GPIOs for
the buttons/keys. The SKU that uses GPIOs is far more common, so we've
decided to support that one upstream.

We aren't actively pursuing Pluto support upstream; it's likely that
I'll send a patch to remove tegra114-pluto.dts in the near future.
