Subject: [PATCH v6 4/4] ARM: tegra: acer-a500: Add Embedded Controller

This patch adds device-tree node for the Embedded Controller which is
found on the Picasso board. The Embedded Controller itself is ENE KB930,
it provides functions like battery-gauge/LED/GPIO/etc and it uses firmware
that is specifically customized for the Acer A500 device.
