arm64: dts: qcom: monaco-evk: Add LVDS display overlay

This commit adds a device tree overlay for the Monaco-EVK mezzanine to support
an LVDS display output. It wires up the Lontium LT9211C DSI-to-LVDS bridge
along with a BOE dual-channel 1920x1080 panel.

[Severity: Medium]
Is the driver support for this panel included in another patch series? 

When this overlay is applied, the driver core will attempt to match this
compatible string against available panel drivers, but no driver currently
registers it and there is no generic fallback provided (such as panel-lvds).

This might cause the panel device to fail to probe, leaving the display
pipeline uninitialized.

[Severity: Medium]
Does this compatible string have a corresponding driver binding?

The existing lontium-lt9211 driver only matches lontium,lt9211. Without 
driver support for lontium,lt9211c, the DSI-to-LVDS bridge device may fail
to match and probe, leaving the display pipeline non-functional.
