Hi Krysztof,

Add bindings for the IMX258 camera sensor.  The bindings, just like the
driver, are quite limited, e.g. do not support regulator supplies.

Changes since v4:
1. Add clock-lanes,
2. Add Rob's review,
3. Add one more example and extend existing one,
4. Add common clock properties (assigned-*).

Changes since v3:
1. Document also two lane setup.

Changes since v2:
1. Remove clock-frequency, add reset GPIOs, add supplies.
2. Use additionalProperties.

Changes since v1:
1. None

This is redundant. Please remove, same for the examples. Can be a separate
patch, too.

Before I remove too much - you mean "clock-lanes" is redundant or entire
set of properties in "port" node?

Just clock-lanes. The rest are just as they should be IMO.
