[V3] ARM: tegra: enable gpio-keys on dalmore

Commit Message

Laxman Dewangan July 10, 2013, 7 a.m. UTC

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.

- Reorder the nodes

Changes from V2:
- Remove unwanted line insertion.
- Rename VolumeUP/Volume down lables.

I have applied this to Tegra's for-3.12/dt branch.
