[RFC][PATCH 2/2 v2] arm: dts: qcom: apq8064-nexus7: Add DSI and panel nodes

[John Stultz <john.stultz@linaro.org>]

Add DSI and panel nodes to get graphics up and running
on the Nexus7.

This still depends on the panel driver being present
along with the rpmclk code.

Feedback would be greatly appreciated!
