The ov08x40 sensor helper is already present, but the sensor has no static
properties. Add its 700 nm unit-cell size, test-pattern mapping and two-frame
delays.

The unit-cell size comes from OmniVision's OV08X product information. The delay
values are experimental and need wider hardware validation.

Build-tested against libcamera base b8910c9a4961 and hardware-tested as part of
the complete patch set on the target HP Spectre.
