[PATCH v3 1/2] dt-bindings: media: i2c: Add Sony IMX678

[Jai Luthra]

Sony IMX678 is an 8.4 Megapixel (3856x2180) CMOS sensor, that can output
pixels over MIPI CSI-2 bus. Add bindings for it.

Changes in v3:
- Use `reset-gpios`, mentioning the sensor XCLR acts like RESETN, instead of `xclr-gpios`
Changes in v2:
- Add per-variant compatibles for mono and colour, alongside the
  generic fallback, so the variant can be declared without powering
  the sensor at probe.
- Rename reset GPIO to xclr as that's what it's called in the
  datasheet, and how it behaves
- Reference the generic video interface devices schema and switch to
  unevaluatedProperties.
- Drop "link-frequencies: true"
- Drop the T: entry for media.git from MAINTAINERS.
