[PATCH 1/7] arm64: dts: qcom: shikra-cqm-evk, shikra-cqs-evk: Add HDMI overlay

[vishnu.saini at oss.qualcomm.com]

From: Mohit Dsor <mohit.dsor at oss.qualcomm.com>

Add a DT overlay for CQM and CQS, to enable HDMI output when LT9611UXD
DSI-to-HDMI daughter card connected to PDISP1 DSI0 on carrier card.
LT9611UXD is connected through I2C4, with reset and interrupt connected
to tlmm GPIO76 and GPIO85.

Disable the default DSI0 panel dt nodes and enable LT9611UXD
bridge for HDMI output.
