[PATCH] arm64: dts: qcom: sc8280xp-huawei-gaokun3: Add dsi panel DT node

[Pengyu Luo]

DSI panel driver have been added for a while, so add the DT node to
enable it. vdd{a,s}-supply for dsi, dsi_phy are blank since the DSDT
describes the wrong, no impact after manual disabling these wrong
supplies.
