Drop #address-cells and #size-cells, which are not required by the
gpio-keys binding documentation, as button sub-nodes are not devices.

While at it, I was told the preferred node naming would be dashes, not
underscores. The deeper we dig, the more we find.

FYI, with "[PATCH] scripts/dtc: Update to upstream version 53bf130b1cdd":
(http://www.spinics.net/lists/devicetree/msg117206.html) applied:

Warning (unit_address_vs_reg): Node /keyboard/button@21 has a unit
name, but no reg property

My v2 GeekBox patch did have *-cells and a reg property, but Julien
asked I drop that: https://patchwork.kernel.org/patch/8246481/

Are you suggesting we should add a reg property here and drop this patch
or go with this patch but follow up to not use @21?
