arm64: dts: qcom: sm6125-xiaomi-laurel-sprout: Enable MDSS and add panel

Browse Source 
Enable the MDSS nodes and add supplies and bindings for the Samsung S6E8FCO
DSI controller for the M1906F9 panel.

The ldo and iovcc gpio pins boot up with a current of 16 mA, but they work
fine with 2mA, so I used that.

mdss_dsi0_phy is powered by VDD_MX, see power-domains in sm6125.dtsi
