ARM: tegra: enable gpio-keys on Dalmore
Dalmore have the keys mounted on board which are connected to different pins of Tegra. Add the keys entry in DTS file to enable key functionality. This will enable KEY_POWER, KEY_HOME, KEY_VOLUMEUP and KEY_VOLUMEDOWN. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Stephen Warren <swarren@nvidia.com>
