[PATCH 7/7] arm64: dts: qcom: lemans-draco-evk: Add Waveshare 8-inch DSI panel overlay

[mohit.dsor@oss.qualcomm.com]

From: Vishnu Saini <vishnu.saini@oss.qualcomm.com>

Add a DT overlay to enable Waveshare 8-inch DSI panel connected to
JDISP1 22pin connector on the carrier card.

DSI0 from SoC is routed through MUX which can be selected by DIP
switch for enabling this 22pin connector. Add the JD9365DA-H3 panel,
GPIO expander at I2C1 mux channel 0 address 0x45 for panel power,
reset and backlight, and the Goodix GT9271 touch controller. DIP Switch
SW2.4 need to be OFF for this to work.

Disable the default HDMI bridge and connector in favour of the
Waveshare DSI panel.
