[PATCH 6/4] arm: dts: qcom: apq8064-nexus7: Add DSI and panel nodes

Tagging on to Archit's patchset here.

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

This still depends on the panel driver being present
(currently under review) along with the rpmclk code.

Feedback would be appreciated here!
