dt-bindings: display: msm: qcm2290-mdss: Use the non-deprecated DSI compat

The "qcom,dsi-ctrl-6g-qcm2290" has been deprecated in
commit 0c0f65c6dd ("dt-bindings: msm: dsi-controller-main: Add
compatible strings for every current SoC"), but the example hasn't been
updated to reflect that.

Fix that.
