arm64: dts: qcom: sm8150-hdk: enable HDMI output

Browse Source 
Add DSI outputs and link them to the onboard Lontium LT9611 DSI-to-HDMI
bridge, enabling HDMI output on this board. While adding the display
resources, also drop the headless ("amd,imageon") compat string from the
GPU node, since the board now has output.
