[PATCH v2 4/6] arm64: dts: qcom: talos-lyra-evk: Add Waveshare 8-inch DSI panel overlay

[anand . tiwari]

From: Shashank Maurya <shashank.maurya@xxxxxxxxxxxxxxxx>

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

DSI0 from SOC is routed through MUX which can be selected by DIP
switch S1016.5 ON, for enabling this 22pin connector.

Add the JD9365DA-H3 panel, GPIO expander at I2C2 address 0x45 for
panel power, reset and backlight, and the Goodix GT9271 touch
controller.

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