The i.MX8MP contains two syscon registers which are responsible
for configuring the on-SoC DPI-to-LVDS serializer. Add DT binding
which represents this serializer as a bridge.

V2: - Consistently use fsl,imx8mp-ldb as compatible
- Drop items: from compatible:
- Replace minItems with maxItems in clocks:
- Drop quotes from clock-names const: ldb
- Rename syscon to fsl,syscon
- Use generic name of ldb-lvds in example
V3: - Add AB from Sam
- Consistently use MX8MP
