[PATCH v4 2/6] ARM: dts: qcom: msm8960: expressatt: Add Light/Proximity Sensor

[Rudraksha Gupta via B4 Relay <devnull+guptarud.gmail.com@kernel.org>]

From: Rudraksha Gupta <guptarud@gmail.com>

Currently the Proximity Sensor doesn't work, but light sensor does.
Left the proximity sensor as a TODO for later.
