The ov08x40 sensor helper is already present, but the sensor has no static
properties. This adds its documented 702 nm unit-cell size and test-pattern
mapping.

The unit-cell size comes from OmniVision's OV08X40 product information. Control
delays remain unspecified so the common defaults are used.

Signed-off-by: James Alexander <opensource@inspiredexperts.com>

Changes in v2:
- Use the documented 0.702 um unit-cell size.
- Map test-pattern value 2 to fading colour bars.
- Use the default control delays.
