[PATCH] arm64: dts: qcom: sc8280xp: Add dsi nodes on SC8280XP

[Pengyu Luo]

The DT configuration follows other Samsung 5nm-based Qualcomm SOCs,
utilizing the same register layouts and clock structures.

However, DSI won't work properly for now (Partial content wrapped to
the left side) until we submit dispcc fixes. And some panels require
DPU timing calculation fixes too. (hdisplay / width timing round errors
cause the fifo error)
