media: ov2680: Do not fail if data-lanes property is absent

Since commit 63b0cd30 ("media: ov2680: Add bus-cfg / endpoint
property verification") the ov2680 driver no longer probes when the
'data-lanes' property is absent.

The OV2680 sensor has only one data lane, so there is no need for
describing it the devicetree.

Remove the unnecessary data-lanes property check.
